If you think to the number of protons in an element atom this number is equal to atomic number of this element.
The calculation of the mass of the proton and other properties are another questions and problems.
The number of protons in an element is equal to the Mass number - this is the number on top C12 .
The Number on the bottom is called the Atomic number C6.
There is not much calculating to do. Simply see what element it is and look it up on the Periodic Table. The atomic number is the number of protons.
The 46 = #Neutrons + #Protons and 22 = #Protons so... # Neutrons = 26
Protons and neutrons; protons and neutrons contain quarks and gluons.
94 protons, 94 electrons, and 150 neutrons
equal to number of protons
18 protons 18 electrons 22 neutrons
11 protons and 12 neutrons
Protons and neutrons= mass
Helium-6 has two protons and electrons and four neutrons.
mass #= # of protons + # of neutrons
Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
The atomic weight minus the number of protons = the atom's neutrons.
There is no way of calculating protons and neutrons from total mass because there is no correlation between the number of porton and neutron.
count the protons and neutrons
Mass number 19 means a total of 19 protons and neutrons. If it has 10 neutrons, that leaves 9 protons, which is Fluorine.
Atomic weight minus number of protons.
The number of protons and neutrons in the nucleus
Neutrons are completely separate from protons, so neutrons do not have any protons, and protons do not have any neutrons.
