Choose the correct answer from the options given below:
Options
A.A, B and C only
B.A, B and D only
C.B, C, and D only
D.A, C and D only
Solution
Sol.A) Heisenberg uncertainty principle is applicable to all the moving microscopic particles.
B) 2pₓ has less value of n thus has lesser size than 3pₓ.
C) E₂s(H) ≠ E₂s(Li)
D) Cr :- [Ar] 3d⁵ 4s¹
Correct statement are A, B and D.
