An atom of atomic number 12and mass number 22 contains how many protons?
The atomic number tells you the number of protons and electrons.
p.s. Subtract the atomic number from the Atomic Mass, and you will get neutrons.
Mass number is the sum of protons and neutrons, so the mass number of an atom that has 12 neutrons and 11 protons has a mass number of 23.
The mass number of an isotope indicates the total number (the sum) of protons and netrons in an atom.The number of protons is determined by the atomic number.The number of neutrons can be found by subtracting the atomic number from the mass number.
The atoms as a perspective of the number of protones in the nuclea. Also the mass of the nuclea is written, as an AMU (atomic mass units).
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
depends on the proton number of the atom, for nitrogen it's 7 so there are 7. The mass number is the number of protons and neutrons so if you subtract the proton number you get the number of neutrons too

In a nitrogen-14 atom, there are 7 neutrons, where the isotopes with mass numbers with 13 and 15, have 6 and 8 neutrons respectively.

the mass number is number of protons in an atom, plus the number of neutrons.
You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
The number of neutrons in an atom can affect the atomic mass of an atom.
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
mass no - atomic no = number of neutrons in an atom.
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
