Period 1 of periodic table
The first electron shell, n = 1, consists of only one orbital, and the maximum number of valence electrons that a period 1 element can accommodate is two, both in the 1s orbital. The valence shell lacks "p" or any other kind of orbitals due to the general l < n constraint on the quantum numbers. Therefore, period 1 has exactly two elements. Although both hydrogen and helium are in the s-block, neither of them behaves similarly to other s-block elements. Their behaviour is so dif… WebJun 23, 2024 · Period 1: H, He (does not follow the octet rule) Period 2: Li, Be, B, C, N, O, F, Ne (involves s and p orbitals) Period 3: Na, Mg, Al, Si, P, S, Cl, Ar (all have at least 1 stable …
