Want this question answered?
Not a question of why. It just is, isotopes have the same atomic number, (which means that they are all the same element) with different neutron numbers.
atoms had gained or lost one or more electron are called ions. so no. the number of neutron and proton don't change. unless it was isotope you are talking about. they have the same atomic number but different atomic mass, which means different number of neutron.
The isotopes of an element must have a different amount of neutrons. I'm pretty sure you know what these are, but just in case: A neutron is a sub-atomic part of an atom, together with protons and electrons.
Atoms have equal numbers of protons and electrons.
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.

Each isotope of an element has a different number of neutrons: Atomic mass of the isotope - Atomic number = Number of neutrons
A proton is a positively charged subatomic particle found in the nuclei of atoms. The number of protons an element has in its atomic nuclei is its atomic number, and defines the element. A neutron is a subatomic particle that has no charge and is also found in the nucleus of an atom. The number of neutrons in the nuclei of an element can vary. Atoms of the same element that have different numbers of neutrons, giving them different mass numbers, are called isotopes.

You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps

No. of neutrons=Atomic mass - Atomic number
Because different elements have different numbers of protons, which determines the atomic number.
