No need to add. Use the elemnts mass number, which is the number of protons plus the number of neutrons
no, they don't. instead they make up the nucleus of the atom. protons and neutrons are made of quarks, which are held together by gluons.which means that the nuceuls and electrons together make the atom.
Neutrons have no charge and contribute to the mass of an atom. They reside in the nucleus along with protons.
Most of the mass of an atom is contained in the nucleus, which is composed of protons and neutrons. Electrons, which orbit the nucleus, have very little mass in comparison to the protons and neutrons.
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.

They're called nucleons. The two types of nucleons are protons and neutrons. Protons are positively charged nucleons and determine, in an atom, what element that atom is. Neutrons have no charge and just supposedly add mass to an atom.
Neutrons have no charge and contribute to the mass of an atom. They reside in the nucleus along with protons.
Protons are positively charged subatomic particles found in the nucleus of an atom, and they contribute to the atom's mass. Neutrons are neutral subatomic particles also located in the nucleus, and they help stabilize the nucleus by balancing the repelling positive charges of protons.

The atomic mass of an atom is equal to the total number of protons and neutrons in its nucleus.
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
If you add the number of protons and neutrons in an atomic nucleus, you get the number of nucleons. This is usually a good approximation to the atomic mass in amu, since both protons and neutrons have a mass that's pretty close to one amu. The number will be slightly off, because electrons contribute as well, protons and neutrons don't have exactly the same mass, and there's something called the atomic mass defect that has to do with the binding energy of the nucleus, but it should be fairly close.
The mass number of an atom is obtained by adding the number of protons and neutrons in the nucleus of the atom. It is a whole number that represents the total number of nucleons in the nucleus.
The number of protons and neutrons controls the weight of an atom.
Add up all the protons and neutrons in the atoms nucleus. OR, look it up on the periodic table.
