A neutral atom has 2K electrons, 8L electrons and 6M electrons. Predict from this:
(a). Its atomic number, (b() total number of s-electrons,
(c). Total number of p-electrons, (d) total number of d-electrons.

Explanation

(a). Total number of electrons `=(2+8+6)=16`
So, atomic number=16
Electronic configuration `=1s^(2),2s^(2)2p^(6),3s^(2)3p^(4)`
(b). Total number of s-electrons`=(1s^(2)+2s^(2)+3s^(2))=0`
(c). Total number of p-electrons `=(2p^(6)+3p^(4))=10`
(d). Total number of d-electrons=0.
