Question

Amongst the following elements (whose electronic configuration an given below) the one having highest ionization energy is
A. `[Ne]3s^(2) 3p^(1)`
B. `[Ne]3s^(2) 3p^(3)`
C. `[Ne] 3s^(2) 3p^(2)`
D. `[Ar] 3d^(10) 4s^(2) 4p^(3)`

Answer 1

Correct Answer - B::C::D
`[Ne] 3s^(2) 3p^(3)` has highest ionisation energy, periodic trend.
