Web29 dec. 2024 · Then, to find the number of neutron, round the atomic mass to the near whole number, so, atomic mass 14.998 round to 15. = (15 – 8 protons) = 7 number of neutrons in the atom. Now, To get the number of neutrons in a Lithium atom, look at its atomic mass which is 6.941 rounded to 7, and the number of protons in Lithium is 3. ∴ … WebWhat is Mass Number? The number of protons and neutrons combine to give us the mass number of an atom. It is represented using the letter ‘A.’ As both protons and neutrons are present in the nucleus of an atom, they are together called nucleons. For example, an atom of carbon has 6 protons and 6 neutrons. Thus, its mass number is 12.
