Do all atoms of a given element contain the same number of protons and the same number of neutrons?

Answer 1

No. Each element may have several different numbers of neutrons in an atom (resulting in isotopes) and there are many of these numbers that are shared, e.g. potassium and calcium both commonly have 20 neutrons.

Answer 2

no i don't believe so. from what i remember in science class the neutrons in an atom are equal to the amount of protons. i may be wrong, but that's what i remember. so, if an atom has 10 protons, it should have 10 neutrons.

This is true for atoms of a low atomic number, but not true for atoms with larger atomic numbers. The major isotope of helium, for example, has two protons and two neutrons. But U-238, the major isotope of uranium, has 92 protons and 116 neutrons.

It has been observed that the more nucleons are in an atom's nucleus, the higher percentage of them must be neutrons in order for the nucleus to be stable. Scientists do not yet have a theory to explain this, although they do have hypotheses.

Answer 3

No, all atoms of a given element have the same number of protons, but they may have different numbers of neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons.

Answer 4

Yes that is true Every atom of a given element does have the same number of protons.

Answer 5

No, only atoms of the same type have the same number of protons, and some atoms of the type have different numbers of neutrons, this are called isotopes. Hope this helps.

Answer 6

They do not however they usually contain the same balance between the two, as far as I know.

Answer 7

All the atoms of a given element contain the same number of protons. However they may have different neutrons and such species are known as isotopes.

Answer 8

yes they do
