Number of protons + Number of neutrons = Mass number(number of nucleons)
Protons and neutrons are contained within the nucleus of an atom. The nucleus is located at the center of the atom and it is where most of the atom's mass is concentrated. Electrons, which are negatively charged particles, orbit around the nucleus in electron shells.
Isotopes have the same amount of protons but a different amount of neutrons.
Every different element has a different number of protons, that is what differentiates it from another element, so there is no answer to your question until you specify which atom you're talking about.
A nucleus with too few nuetrons is unstable because there are not enough to keep the protons. There must be a certain amount of nuetrons for every element.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
The number of protons.
An atom is a nucleus of protons and neutrons with electrons orbiting around. An element is an atom with a specific amount of protons, neutrons, and electrons. A molecule is a bunch of atoms stuck together.
Protons and Neutrons are found in the Nucleus of the Atom. An atom's atomic number corresponds to the amount of protons (differnt amount of protons=different element). There are usually the same amount of Neutrons and Protons, but in some cases theere are more Neutrons (these are called different isotopes).
Number of protons + Number of neutrons = Mass number(number of nucleons)
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
The Atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element that specific element. Actually, it is only the protons. The number of neutrons and/or electrons can vary, and it is still the same element. The one thing that makes an element that specific element is only the number of protons.

Isotopes have the same amount of protons but a different amount of neutrons.
The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
Every different element has a different number of protons, that is what differentiates it from another element, so there is no answer to your question until you specify which atom you're talking about.
Atomic number indicates the amount of protons present in the nucleus of an atom.
