How do you subtract neutrons in an atom?
Subtracting neutrons from an atom is done through a process called neutron capture or radioactive decay. Isotopes naturally lose neutrons through radioactive decay, converting into a different element in the process. Scientists can also create specific isotopes by bombarding atoms with particles in a laboratory setting.
Do many atoms make up an element?
The nucleus of an atom is made from a certain number of protons and in most cases neutrons. This determines the type of atom or element that the substance is. Differing numbers make for the different elements in the periodic table. The number of electrons in an atom is equal to the number of protons in the nucleus unless the atom is ionised. Differing numbers of neutrons make different isotopes of the same element. It should be emphasised that this is a very simplistic explanation and further research should be done for a more complete answer.
How many neutrons are in water?
In a single molecule of water : 10 protons (1 from each hydrogen and 8 from oxygen)8 neutrons (none from hydrogen and 8 from oxygen)water = H2O 10 electrons (1 from each hydrogen and 8 from oxygen)To work out how many electrons, protons and neutrons in a molecule;Find the ballenced chemical equation - H20 in this caseLook up each element in the periodic table - hydrogen and oxygen in this caseCount the electrons, protons and neutrons - you do this by looking at the top numbers and the bottom numbers for each element. The top number is the "atomic weight" of the element, so the total number of protons and neutrons as each 1 unit of mass. The bottom number is the "proton number" number of electrons and protons (each) so for oxygen where the number is 8, there are 8 protons and 8 electrons. To work out the number of neutrons simply take the bottom number from the top number as you are taking the number of protons away from the total weight to give you whats left, which is the number of protons.Do a little bit more adding - H2O = 2 + 8 electrons= 2 + 8 protons= 0 + 8 neutronsAnd your done. Easy
What makes up most of the volume of an atom?
the electron cloud. some people say that's its mostly made up of "nothing" , but that is incorrect. it has to have SOMETHING in it or else it wouldn't be an atom, no? and yes i have done research on this, so i know that my answer is 100% accurate.
What determines the vast majority of characteristics in an atom?
It is often said that electrons give atoms their own peculiar 'personality'. Since potassium has one outer electron/valence electron, it tends to lose it and thus render the atom a cation. Fluorine on the other hand needs one electron to fill up its valence shell and so gains an electron, yielding an anion. The number of electrons in the valence shell determines the reaction-'personality' of an atom. Nitrogen requires three electrons in its valence shell to fill it up (obey the octet rule) and this can be easily done by bonding with 3 hydrogens. Carbon, to obey the octet rule, needs 4 electrons. It binds in a myriad of ways - in organic chemistry - to hydrogen, oxygen, nitrogen.... Carbon is said to be hugely 'promiscuous'. It has the ability to bind with so many atoms in so many ways. Carbon is the backbone of carbon chains (with hydrogen: hydrocarbons), strings of carbon atoms that form phospholipids and nucleic acids, the stuff of life. All this bonding and chain forming is determined by the 'personality' giving electrons. But there are also the nuclear nucleons (protons and neutrons) to consider. The more protons, the greater the attraction to the electrons. This is unless an outer shell has a single electron (like lithium or potassium) in which case the electron is still free to rush away from the attractive nucleus, increasing the area it is likely to exist in and in effect enlarging the atom. The greater the number of electrons in an outer shell (like fluorine) the more effect the nucleus has - a summing effect on all the electrons and effectively shrinking the atom due to the summed nuclear effect on the electrons. Neutrons give the 'isotope' personality. The greater the number of neutrons the greater the mass of the atom. All atoms of a single element differ not in the number of protons (for example all iron atoms always have 26 protons and all uranium atoms always have 92 protons) but may differ in the number of neutrons. Instability is gleaned in a nucleus if too many neutrons are present. An unstable nucleus is a radioactive nucleus. For example the carbon isotope Carbon-14 has the most neutrons of any carbon isotope and is thus the unstable one. Electrons, protons and neutrons all give characteristics to differing atoms. Since all elements differ in their neutron, electron and proton numbers, each element gleans its characteristics from this. Its atoms gain their own identity!
How do you subtract neutrons in an atom?

Isotopes naturally lose neutrons through radioactive decay, converting into a different element in the process. Scientists can also create specific isotopes by bombarding atoms with particles in a laboratory setting.
How can one create an atom?
Creating an atom involves combining protons, neutrons, and electrons in a specific arrangement. This can be done through processes like nuclear fusion or particle accelerators. The specific elements and their arrangement determine the type of atom created.
How do you complete the mass number given the number of protons?
This cannot be done because the atomic mass number also depends on the number of neutrons. Different isotopes of an element have different numbers of neutrons. You just add up the number of protons and neutrons to get the atomic mass number (simple!). For example, neon-20 has 10 protons and 10 neutrons, but neon-22 has 10 protons and 12 neutrons. In the most famous case, uranium-235 has 143 neutrons per atom, but uranium-238 has 146 neutrons. Both isotopes have 92 protons per atom. This 92 is what makes them both uranium.
determine the subatomic particle ( electron, protons, neutron)?
For Example:- Calculate the number of protons, electrons, neutrons in Bromine with atomic number 35 and mass number 80. Hint: In order to answer this question you must recall the periodic properties and mole concept chapter in which you have done conversions regarding the number of moles, number of atoms, number of electrons, protons, and neutrons in a sample of given atomic number and mass number. Firstly, find the number of protons and the same number of electrons will be there and the sum of protons and neutrons form the mass number and you will get your answers. Complete step by step answer: Step 1: In this step we will find the number of protons of the given sample: Number of protons of a sample = Atomic Number of the element = 35 Step 2: In this step we will find the number of electrons of the given sample: Number of electrons of a sample = Number of protons = 35 Step 3: In this step we will find the number of neutrons of the given sample: Number of neutrons of a sample = (Mass number - Atomic Number) of the element Number of neutrons of a sample = 80 – 35 = 45 So, here we got our required values. The values are: No. of proton p = 35 No. of neutron n = 45 No. of electron e = 35 Note:The number of protons in the nucleus of the atom is equal to the atomic number (Z).The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Do neutral lithium atoms contain more neutrons than protons?
Neutral lithium atoms contain more neutrons than protons. A lithium atom typically has 3 protons in its nucleus, giving it an atomic number of 3, and it usually has 4 neutrons which adds to the mass number of 7.
What is an atom that differs from other atoms of the same element by the same number of neutrons in its nucleus?
It is called an Isotope if you're looking for a quick answer. But to go more in depth you need a bit of background knowledge: An element is determined by the number of protons it has in its nucleus. For example Carbon has 6 protons. Only atoms of carbon will have 6 protons. Atomic mass is measured by the number of protons and neutrons which weigh the same amount. Scientists use a unit called AMU or Atomic Mass Unit which is the equivalent to the weight of 1 proton or 1 neutron. The definition of an isotope is an element with the same number of protons as another, but a different number of neutrons. Here's an example: Carbon-12 and Carbon-14 are two naturally occurring isotopes of Carbon. Both have 6 protons. The numbers stand for the atomic mass of that isotope. Because we know there are 6 protons in the atom, and that protons and neutrons weigh the same amount, we can determine the number of neutrons. 12 (combined neutrons and protons) - 6 (known number of protons) = 6 neutrons The same can be done with the other atom 14-6 is 8 neutrons. Therefore we know that isotopes are the atoms of the same element, with different atomic mass, which is caused by a higher or lower amount of neutrons
How do you alter nucleus of an atom?
The nucleus of an atom can be altered through processes such as nuclear reactions, which involve changing the number of protons and neutrons in the nucleus. This can lead to the formation of different elements or isotopes. However, altering the nucleus of an atom can release large amounts of energy and needs to be done carefully to control potential risks.
When an atom ionizes it does what?
In order for an atom to become an ion, removing or adding an electron should be done. The mass number remains the same because this indicates the number of protons and neutrons and not of electrons.
Two neutrons added to an atom of the element iridium result in?
If it is possible without any other nuclear reactions to be done, it'll give you an isotope of iridium.
When a radioactive nucleus gives off a gamma ray it's atomic number increases by?
Emission of a gamma ray does not change the atomic number of the atom. A gamma ray is a photon, and has no mass. The atom's mass is reduced by the conversion of a tiny amount of mass into the energy of the gamma ray. This changes neither the number of protons nor the number of neutrons. It is done by rearranging the nucleons, changing the state of excitation of the nucleus. An example is when 99mTc emits a gamma ray and changes to 99Tc.
What is used to determine the number of each atom in an iconic formula?
The number of each atom in an ionic formula is determined by the charges of the ions involved and their ability to balance each other. This is done by using the principle of charge neutrality, where the total positive charge from cations must equal the total negative charge from anions. The ratio of ions is adjusted accordingly to achieve this balance, resulting in the simplest whole-number ratio of each type of atom in the formula.
