Its the mass number of an atom.
The mass of an atom is concentrated in the nucleus. Both protons and neutrons which are collectively known as nucleons are found within the nucleus.
Mass of electrons are not considered to be contributing towards the mass no. of an atom as their size is small and thus their mass is negligible.

What is the Number of protons in an atom is called the atomic?
The Atomic Number. Remember the Atomic Number, of an elements is ;- #1 The position in the Periodic Table #2 The number of protons in the nucleus #3 The number of electrons in the neutrally charged atom. NB Do NOT confuser Atomic Number with Atomic Mass. Atomic Mass the total number of nucleons in the nucleus of af an atom. Nucleons is the collective noun for the sum of all the protons and neutrons in the nucleus.
Where is most of the mass of an atom within the nucleus or outside of the nucleus?
The whole is less than the sum of the parts. A proton or neutron (nucleon) will have less mass in a nucleus that outside it. That's because some of the mass of a nucleon is converted into binding energy to hold an atomic nucleus together. That's the so-called mass deficit. Oh, and before we go, a proton or neutron is called a nucleon only inside the nucleus of an atom. We don't apply that term to either one when they're outside the nucleus.
What is the total number of subatomic particles in the nucleus of an atom bi?
In this case, the number 209 represents the sum of protons + neutrons.
What is an atom's mass number?
The sum of the protons and neutrons in the nucleus
What Particles responsible for the mass of atom?
The three main sub-atomic particles of an atom are proton, neutron and electron. The mass of a proton is about 1800 times the mass of an electron and the masses of proton and neutron are almost similar. Hence, mass of only proton and neutron is counted towards the mass of an atom.
The sum of the numberof protons and nuetrons in the nucleus of an atom?
The sum of the number of the protons and neutrons in the nucleus of an atom is called as atomic mass.
What represents the sum of proton in the nucleus of an atom?
mass number
Why do the mass of atom depend upon the nucleus?
because the atomic is the sum of no of proton and no of neutron
What is the sum number of protons and nuetrons in the nucleas of a atom?
The Mass Number.
What is the sum of the number of protons and the number nuetrons in an atom?
mass number
The number of protons and nuetrons in the nucleus of an atom?
The atomic mass number or nucleon number. The atomic mass number is written in superscript on the left of the elements symbol.
