The maximum electron capacity for each energy level is given by 2n^2.
According to the Bohr model of the atom, electrons are arranged in energy levels in an atom. The energy levels are arranged in increasing order as we go farther away from the nucleus.
The maximum electron capacity for each energy level is given by 2n^2. Hence, when;
n = 2, the maximum electron capacity is 2 electrons
n =2, the maximum electron capacity is 8 electrons
n=3, the maximum electron capacity is 18 electrons
n = 4, the maximum electron capacity is 32 electrons
