Question

Which of the following relation is correct for boron element? Here P = period number of boron
N = number of valence electrons is boron
A. `(P+1) gt N`
B. `(P+1) lt N`
C. `(P+1) = N`
D. `P = N`

Answer 1

Correct Answer - C
`B-overset(1s^(2)2s^(2)2p^(1))hArr` Period `P = 2`
`P +1 = 3 rArr` same values `N = 2+1 = 3`
