Mass number is about the neutrons and protons. The total of neutrons and protons.
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
No it is not the atomic number. We call it mass number.
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
Number of neutrons = Mass number - atomic number = 210 - 82 = 128
One doesn't generally "calculate" the number of neutrons. The number of neutrons in an atom is always equal to the number of protons, and the number of protons can be found on the Periodic Table of Elements, which can easily be found on the internet or in a science textbook.
yes mass can be a number
Number of neutrons = Mass number - atomic number
To find the mass number of an element, add together the number of protons and neutrons in the nucleus of an atom. The mass number is typically written as a superscript to the left of the element symbol.
To find the number of neutrons from the mass number, subtract the atomic number from the mass number. The atomic number represents the number of protons in an atom, and by subtracting it from the mass number, you can determine the number of neutrons present.
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
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.
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.

Mass number = Number of protons + number of neutrons
Mass number = number of protons + number of neutrons in an atom
