How to predict the no. of period, group and block of a given element, when its atomic no. is known to us. Please tell according to the level of class 11th and class 10th both.I Know there was one method according to the electronic configuration we knew in class 10th, but now it should be more advanced so pls tell with example.

Differnce and similarity between electron gain enthalpy and electronegativity ?

Subject: Chemistry, asked on 12/12/16

I am not getting this question. If we go and see the electronic configuration then sulphur has p6 orbital so electron gain enthalpy should be more positive in that case or is more positive means less EGE????
