Question

And element X has 12 protons and neutrons in the nucleus find the atomic number ,mass number 24 and number of electrons

Answer 1

Answer:

Mass number = number of proton + neutron = 24

Atomic number = number of protons = 12

number of electrons = number of protons = 12...

Answer 2

Answer:Mass is denoted as A

mass of atom=number of neutron +no of proton if mass given 24 and proton given 12 so neutron =24-12=12neutrons

No of protons =no of electrons in a atom always it will differ only electron when atom is a charged ion so if proton is 12 then electron is also 12

In a atom the atomic no we can get by how many protons it have if it have 12 proton so atomic no is also 12.

this atom is of magnesium or in short it is Mg
