Question

The electronic configuration of some neutral atoms are given below:
(A) 1s2 2s1 (B) 1s2 2s2 2p3
(C) 1s2 2s2 2p5 (D) 1s2 2s2 2p6 3s1
In which of these electronic configuration would you expect to have highest IE1 and IE2 respectively
(1) C,A (2) B,A (3) C,B (4) B,D​

Answer 1

Answer:

1. the highest ionisation energy can be explained through as the energy required to give away an electron so losing electro is easy in A AND D BUT DUE TO THE PRESENCE OF S ORBITAL B IS THE ANSWER
2. THEREFOREE THE ANSWER MIGHT BE SECOND "B & A"

Answer 2

Answer:

2) B A

Explanation:

1) Half filled orbital is more stable than partially filled orbital therefore B) 1s2 2s2 2p3

2) after removal of 1e from each of the following the A) has configuration as 1s2 which is the stable noble gas configuration ( helium).

More stable configuration higher is its ionisation potential.
