Detailed explanation-1: -Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
Detailed explanation-2: -The first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.
Detailed explanation-3: -The 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons.
Detailed explanation-4: -The first shell can only accommodate one orbital, thus the maximum number of electrons in the first electron shell is two. The second and third shells each contain four orbitals and can therefore accommodate 8 electrons each.
