What is the opposites of an isotope?
The opposite of an isotope would be a pure element that does not contain any variations in the number of neutrons in its nucleus. This means that all atoms of that element have the same number of protons and neutrons.
To balance a chemical equation, make sure the number of atoms of each element is the same on both sides. For example, in the equation _H2 + _O2 -> _H2O, the coefficients would be 2, 1, and 2 respectively. This balances the equation because there are 2 H atoms and 2 O atoms on each side.
How many protons and newtrons are there in16O8 and 56Fe26?
The atomic number of Oxygen is 8 and hence it has 8 protons and 8 electrons.
Oxygen has a mass number of 16. The number of neutrons is obtained my subtracting the number of protons from the mass number, i.e., 16-8 = 8. Therefore, Oxygen has 8 protons as well as 8 neutrons.
Now, Fe (Iron) is an interesting element. It has many isotopes. So, the exact number of neutrons is an estimated value. However, since the mass number has been given (56) we have to only determine the number of neutrons for this isotope of Iron. The number of protons is the same as the atomic number i.e., 26. The number of neutrons is obtained by subtracting the number of protons from the mass number , i.e., 56-26 = 30.
Therefore, according to the given data, Oxygen has 8 protons and 8 electrons. Iron has 26 protons and 30 neutrons.
What are atoms consits consist of?
Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons. Protons carry a positive charge, neutrons carry no charge, and electrons carry a negative charge. The arrangement of these particles determines the properties of the atom.
How many neutrions does calcium have?
The alkaline earth metal calcium has 20 protons in its nucleus. That's what makes it calcium; it's what gives it its elemental identity. It's in Group 2 of the periodic table. The number of neutrons in calcium varies, however, and there are several different isotopes of this metal. The four stable isotopes of calcium (Ca) are Ca-40, Ca-42, Ca-43 and Ca-44, which have 20, 22, 23 and 24 neutrons in their nuclei, respectively. About 97% of naturally occurring calcium is Ca-40.
There are a number of other isotopes of calcium, and they range from Ca-34 to Ca-57. It should be noted that Ca-46 and Ca-48 have extremely long half-lives, and are pretty stable. The interesting isotope is Ca-41, which is produced by neutron capture from Ca-40. This makes it of interest in the study of stars. Use the links below for more information.
In general, calcium is said to have an estimated 20 neutrons.
How many carbon atoms are in the graphite unit cell?
there are many different atoms some are called sex cells bloood cells white blood cells and many more cells...yeah this is a cell's answer not an atom answer muhahahahahha biach you got wasted!
What does adding heat to matter cause the atoms to do?
Adding heat to matter causes the atoms to vibrate faster and increase in kinetic energy. This can result in the matter changing states, such as melting from a solid to a liquid or evaporating from a liquid to a gas.
Atoms have always and will always move unless, in the future, we find a way to get a substance to a temperature of absolute zero, 0 degrees Kelvin. Because the moving of the atoms creates heat.
What do atoms form when they stick together?
Atoms form molecules when they stick together through chemical bonds. Molecules are the smallest units of a compound that can exist independently and possess unique chemical properties based on the atoms they are composed of.
What are molocules of carbon atoms that form in layer?
Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice structure. Carbon atoms in graphene are bonded together in a single layer, making it an example of a two-dimensional material with unique properties due to its hexagonal arrangement.
What atoms have no overall charge?
Atoms with no overall charge are called neutral atoms. They have the same number of protons, which carry a positive charge, and electrons, which carry a negative charge. This balance of positive and negative charges leads to a neutral overall charge for the atom.
How do you make an edible atom?
To make an edible atom model, you can use various edible materials to represent the parts of an atom. For example, you can use different flavors of candy for protons, neutrons, and electrons, and arrange them to match the structure of the atom you are trying to represent. Be creative and have fun with it!
Which nonmetal is a good conductor of electricity?
Graphite.
You might have come across experiments using a pencil to complete a simple circuit to check if a bulb glows and you might have observed that it does.
The graphite in the lead of the pencil is what helps conduct electricity.
Why is an atom not really indivisible?
An atom was once thought to be indivisible, but modern science has shown that atoms are made up of even smaller particles called protons, neutrons, and electrons. The discovery of subatomic particles through experiments such as particle accelerators has disproven the idea of atoms being indivisible.
Why is an atom not really in invisible?
Atoms are not invisible because they can interact with light, which allows us to see them using tools like microscopes. Light can be absorbed, emitted, or scattered by atoms, providing us with information about their presence and behavior.
What is mean by law hydrogen electrode?
The standard hydrogen electrode (SHE) is a reference electrode that is used to determine electrode potentials for other half-cell reactions. It has an assigned potential of 0 V at all temperatures. The SHE consists of a platinum electrode immersed in a solution of 1 M HCl and is in equilibrium with hydrogen gas at a pressure of 1 atm.
Shell was founded in 1907. The company originated from a merger of Royal Dutch Petroleum Company and the Shell Transport and Trading Company.
What 3 atomic anions have 9 protons?
Since you want atomic (rather than molecular) anions AND 9 protons only the element with atomic number 9 is possible, i.e. Fluorine. This has really only one anionic state though, -1. So I can only suppose you mean either:
- transient unstable anions
- synthetic isotopes of Fluorine (also unstable)
- molecular rather than atomic anions
In the latter case (most likely) you could have as well as F- also e.g. NH2- or OH- as molecular (not atomic) anions with 9 protons in total.
Why does not an atom form more than three bonds?
I don't know because the statement is (in general) NOT true. Who told you so?
For instance:
KMnO4, in which the central Mn has 7 bonds: one single (-) and three double (=) bonds, binding 4 other atoms (O).
(K-O-)Mn(=O)3
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons.
It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10.
thus, fluorine has 9 protons and 10 electrons.
Do cells combine to make atoms?
No, cells do not combine to make atoms. Atoms are the building blocks of all matter, including cells. Cells are made up of a combination of different atoms, such as carbon, hydrogen, oxygen, and nitrogen, organized into molecules that form the structure and function of the cell.
Is Xe 6s24f145d106p2 a possible ground state electron configuration?
No, this is not a possible ground state electron configuration. It violates the Aufbau principle, which states that electrons fill orbitals starting from the lowest energy level. The correct electron configuration for xenon (Xe) is 1s22s22p63s23p64s23d104p6.
Is Xe6s25d106p4 a possible ground state electron configuration?
No, Xe 6s2, 5d10, 6p4 , this is not ground state of any Xe descendant.
In fact it is an impossible electron configuration, because the 4f-block is missing, which should be filled in before 6p block at the 'end' of the 6throw,
so it even isn't 84Po [Xe] 6s2 4f14 5d10 6p4 .
Xenon ground state is in short note: [Kr] 5s2 4d105p6
In full: [1s2, 2s2 2p6, 3s2 3p6 3d10, 4s2 4p6] 5s2 4d10 5p6
Radon ground state is in short note: [Xe] 6s2 4f145d10 6p6
In full: [1s2, 2s2 2p6, 3s2 3p6 3d10 3f14, 4s2 4p6 4d10, 5s2 5p6] 6s2 4f14 5d10 6p6
What flows from atom to atom to make electricity?
In metals, electricity flows through the movement of free electrons from atom to atom. These electrons can move easily through the material, creating an electric current.
What atom number tells how many of these particles are in an atom?
The bigger number (Atomic mass) is the amount of protons (=same amount of electrons unless specified) and nutrons in an atom. The smaller number (atomic number) is the amount of protons only
