The number of protons and neutrons added together gives the Atomic Mass number, nucleon number or often simply the mass number".
This is DIFFERENT from the (relative) atomic mass, once called atomic weight, which is the average mass of the naturally occurring isotopes of an element in a sample relative to 1/12 th mass of carbon-12.

The number of neutrons plus protons in the nucleus of an atom-?
nass number is the number of neutrons plus protons in the nucleus of an atom
Does the nucleus of an atom have protons neutrons electron?
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.
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
Is this statement correct atoms are made up of nucleus and electrons composed of protons whose number is called the atomic number and neutrons whose numbers added together make the mass number?
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
Protons and neutrons in the nucleus add up to give the?
The number of protons added to the number of neutrons in a nucleus give that isotope's atomic weight.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.

It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
How is the mass number determine?
the mass number is determined on the number of protons and neutrons in the nucleus of the atom.
Does a nucleus have the same number of protons and electrons?
The nucleus of an atom contains only protons and neutrons; there are never any electrons in the nucleus. The number of neutrons is generally equal to or greater than the number of protons.
Protons and neutrons in the nucleus add up to give the?
The number of protons added to the number of neutrons in a nucleus give that isotope's atomic weight.
Total number of particles in the nucleus is called what?
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
Is the atomic number of an atom is equal to the number of protons or neutrons in the nucleus?
Protons
What do isotopes and nucleus have in common?
All the isotopes of a chemical element have the same atomic number, number of protons and number of neutrons.
Can the nucleus hold two or more protons?
A nucleus contain protons and neutrons. A nucleus can hold more protons - the number is equal to atomic number.
