How many protons and neutrons and electrons does the element gold have?
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
How many subatomic particles does krypton have?
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
How many protons neutrons and electrons does Fe-56 have?
It doesn't matter if it's 56Fe or 49Fe; the number of protons in an atom of iron will remain constant. Why? Because if there was one more electron, it wouldn't be Fe anymore: it'd be cobalt (Co). The number of protons determines the element, the only thing that can change regarding the nuclear makeup of an atom without changing the element is the number of electrons. The 56 stands for the atomic weight of that particular isotope of iron. If each neutron and each proton weigh 1 amu each, then the atomic weight minus the number of protons will give you the number of neutrons.
How many protons electrons and neutrons in calcium-44?
Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.
What subatomic particles could be changed without changing which element the atom is?
The element that an atom is is determined by the number of protons. The number of electrons can be changed (creating an ion), and the number of neutrons can be changed (creating an isotope), and as long as the number of protons does not change, the element that the atom is does not change.
How many protons and neutrons and electrons does the element gold have?
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
What effect produced by changing the number of neutrons in the nucleus of an atom?
What differentiates one element from another (like Hydrogen from Helium) is the number of protons in the nucleus. When protons are added (as happens in nuclear fusion) or subtracted (nuclear fission), the element transmutes into another element. When the number of Protons are changed, both the Electrons and Neutron (numbers) will change too. Protons are paired with electrons. Protons + Electrons = Neutrons, thus reinforcing that both the Electrons and Neutrons will change when the number of Protons has.
Why doesn't the number of protons change for a single element while the neutrons and electrons can?
Because the no. of protons is the primary property through which we call an atom to be of a particular element.
Which particles that make up an atom are involved in nuclear reactions?
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.
What part of an atom must change for the atom to become a new element?
An atom must gain or lose protons from its nucleus to become an atom of another element. The number of protons, and to a much lesser extent the number of neutrons, will determine the chemical properties of an element.
What subatomic particles could be changed without changing which element the atom?
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
What can be added or taken away from an atom to change the atomic mass?
The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.
How many subatomic particles does krypton have?
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
Do carbon-12 and carbon-14 have the same number of protons?
yes no matter what the same element will have exactly the same amount of protons only the neutrons and electrons change!
An atom does not have to have equal numbers of?
An atom does not have to have equal numbers of protons and electrons, but it needs to have the same number of protons and electrons to be electrically neutral. Having an unequal number of neutrons in an atom will result in isotopes of the same element with different atomic masses.
Are the number of protons always equal to the number of neutrons?
No, in fact, they rarely are equal. There are different forms of the same type of atom. For example, there are three isotopes of Hydrogen, an element that has one proton. Hydrogen-1 has no neutrons. Hydrogen-2 has one neutron. Hydrogen-3 has two neutrons.
Does an atom retain the chemical identity of an element?
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
