The number of neutrons present in atoms of an element may differ. Atoms of an element which have different numbers of neutrons are called isotopes. These differ in mass but have the same chemistry.
All of the neutrons in the nucleus of an atom are the same.
All the isotopes of an atom have the same number of protons but different number of neutrons.
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
The nucleus of an atom is the central part of an atom containing practically all the mass of the atom. The nucleus is composed from protons and neutrons.
All neutrons have a negative charge. That is the reason they are called neutrons.
Actually, all atoms have neutrons except for one, and that is the normal hydrogen atom, which is only comprised of a single proton and electron.
All the isotopes of an atom have the same number of protons but different number of neutrons.
The hydrogen atom has no neutrons in the nucleus. There is just a proton and an electron.
The sum of all Protons and Neutrons.
All the isotopes have a different number of neutrons in the nucleus.

Protons and neutrons. Virtually all of the atom's mass.
Protons and neutrons. Virtually all of the atom's mass.
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.
