# What determines the number of atoms in an element?

## Related Questions

YesAnswerThe number of protons determines the element, the number of neutrons with that number of protons determines the isotope (isotopes are atoms with the same number of protons but with different number of neutrons) and the number of electrons determines the ionization state.

The number of protons present in each atom of an element determines the atomic number of the element.

The atomic number is the number of protons in the atoms of a particular element. The number of protons determines the atomic number.

All atoms of the same element have the same number of protons. Atoms of different elements have different numbers of protons. The number of protons determines the element.

The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.

The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.

The atomic number determines the element. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number, which identifies it as that element.

IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.

The elements are arranged on the periodic table according to their atomic numbers. The atomic number of an element is the number of protons in the nuclei of its atoms. So the number of protons in the nuclei of its atoms determines its place on the periodic table.

The number of valence shell electrons will generally determine the bonding characteristics of the element in question.

These atoms would be different isotopes of that element. Protons determine which chemical element we have, and neutron count determines which isotope of that element we have.

Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.

No, by definition two atoms with the same number of protons are the same element. The number of protons determines which element an atom is.

All atoms of a given element have the same number of protons in a nucleus. It is the number of protons in an atom's nucleus that determines the elemental identity of any atom. Period.

Yes. Each element's atoms all have the same unique number of protons, which is what defines an element and chiefly determines its chemical properties.

Yes. The atomic number is the number of protons in the nuclei of an element's atoms, which is unique to each element and determines the element's identity.

The number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.

Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.

The number of protons, which is the atomic number of an element, determines the identity of an element.

Isotopes are atoms of the same element, but have a different number of NEUTRONS. Example- Carbon-14

proton you can change the number of neutrons and electrons and still have the same element

the number of protons determines the atom.
