I have two questions:
It's said that in p block there's gradation in physical and chemical properties of elements. What is meant by this statement?
Why are the different blocks named s, p, d and f?

First question
From P.248, Rudiments of Chemistry:
'p' block elements contain both metal and non-metal and we observe a gradation of properties (such as electropositivity, electronegativity, reducing or oxidising property etc.) as we move from left to right in a period.
Second question
From the Wikipedia article on atomic orbital:
They are derived from the description by early spectroscopists of certain series of alkali metal spectroscopic lines as sharp, principal, diffuse, and fundamental. Orbitals for ℓ > 3 continue alphabetically, omitting j (g, h, i, k, …)

$\begingroup$ Aren't trends followed in every block?If yes,why did my teacher tell that point only for that specific block? $\endgroup$ Sep 6, 2016 at 16:07

$\begingroup$ @AbhijithDileepKumar That would be something you should ask your teacher. $\endgroup$– DHMOSep 6, 2016 at 16:09

$\begingroup$ I am sorry.But could you tell me what "complexes"are in chemistry? $\endgroup$ Sep 6, 2016 at 16:24

$\begingroup$ @AbhijithDileepKumar Make that a separate question with sufficient context (where do you see this word? can you quote the whole sentence?) $\endgroup$– DHMOSep 6, 2016 at 16:37
