Atoms of two adjacent elements in the periodic table are in the ground state. Both atoms have a total of 10 d electrons. Atom A has no p electrons in its valence shell but atom B has one electron in the p subshell of its valence shell. Element A is ___ and element B is ___.
From given information we can say that
Valence electronic configuration of element A is:- 4s23d10
So element A is having atomic number of 30 so it represent Zinc.
Valence electronic configuration of B is:- 4s24p1
Element B have atomic number 31 so it is Galium.
