Explain, in terms of electron shells, why the radius of a K atom is greater than the radius of an Na atom. Their salts are present in sea-water and hence they are collectively known as halogens (Greek, Halos means sea salt producers). Synthetic and Natural Polymer; p-Block Group 15 Elements (Nit.. In this manner, in these elements, the n p subshell is step by step filled. In the iotas of p-block elements, the separating electron enters the valence p subshell.
