Atomic number for magnesium is
As per Bohr's model the electrons could be arranged inside the atom as per following
- Each shell or energy level can contain only a fixed number of electrons.
- The general formula proposed by Bohr was that the
#n^(th)#shell can contain up to #2(n^2)#electrons. Where #n=1,2,3....#and is the shell number.
- The first shell can hold up to two electrons
- The second shell can hold up to eight electrons
- The third shell can hold up to eighteen electrons and so on.
