Boron ends in 2p1. In group 4A or 14, all elements end in p2. And so it goes. Compare, for example, the 1s case (H 1s 1 vs. Li 2s 1 & F 2p 5; and He 1s 2 vs. Be 2s 2 & Ne 2p 6) with the 4f case (the 15 lanthanoids La–Gd and Gd–Lu are chemically similar to Ac and the later actinoids Cm–Lu, whereas the early actinoids Th–Am are more or less akin to d elements Hf–Ir).

Click here👆to get an answer to your question ️ The electronic configuration of an element is 1s^2, 2s^2, 2p^6, 3s^2, 3p^3 . Which is the atomic number of the element which is just below the above element in the periodic table?
principal quantum number d The 1s2 is from the first period with Hydrogen and Helium. The 2s2 is from the second period Lithium and Beryllium.
One orbital holds two electrons spinning in different directions, + and -. So 2s is filled with a + and a - electron. In each energy level there are three p orbitals. Hund's rule states that each orbital first is filled with one electron and when all orbitals contain one electron the electrons will start filling the rest of the orbitals.
