The first ionization potential of Be and B will be:
1. 8.8 and 8.8
2. 6.6 and 6.6
3. 6.6 and 8.8
4. 8.8. and 6.6
An electronic configuration that has maximum difference between II and III ionization potential is:
1. 1s2 2s2 2p6 3s1
2. 1s2 2s2 2p6 3s2
3. 1s2 2s2 2p6
4. 1s2 2s2 2p5
The correct order of IP(ionization potential) among the following elements Be, B, C, N, O is:
1. | B < Be < C < O < N | 2. | B < Be < C < N < O |
3. | Be < B < C < N < O | 4. | Be < B < C < O < N |
Incorrect order among the following is:
1. | NH3 < PH3 < AsH3 – Acidic |
2. | Li < Be < B < C – Ist Ionization potential |
3. | Al2O3 < MgO < Na2O < K2O - Basic |
4. | Li+ < Na+ < K+ < Cs+ - Ionic radius |
