Question

Which of the following relation is true?

(Max denotes the maximum number of electrons. K, L, M, N represent the shells)

• A. $Max\left(N\right)+Max\left(L\right)=2\left(Max\right(K)+Max(M\left)\right)$
• B. $Max\left(N\right)+Max\left(L\right)=Max\left(K\right)+Max\left(M\right)$
• C. $2\left(Max\right(N)+Max(L\left)\right)=Max\left(K\right)+Max\left(M\right)$
• D. $Max\left(M\right)+Max\left(L\right)=\left(Max\right(K)+Max(N\left)\right)$

Answer 1

The correct option is A $Max\left(N\right)+Max\left(L\right)=2\left(Max\right(K)+Max(M\left)\right)$

$Max\left(M\right)=18,Max\left(N\right)=32,Max\left(L\right)=8,Max\left(K\right)=2$.

Now substituting the value in A we get

$LHS=32+8=40$

$RHS=20\times 2=40$
