Answer to Question #122203 in General Chemistry for Ronak kapoor

Question

In which of the following has maximum ionisation energy gap in between 1st and 2nd metal options are (a) 1s² 2s² 2p6 3s¹ (b) 1s² 2s¹ please answer me?

Answer 1

1s² 2s² 2p⁶ 3s¹ The element with the electronic structure is Na. The element with the electronic structure 1s² 2s¹ is Li.

The ionization energy increases from bottom to top and from left to right in the periodic table of chemical elements. it can be seen that the ionization energy of Li (5.39 e-V) is higher than the ionization energy of Na (5.14 e-V).

Answer: 1s² 2s¹ that is Li’s ionization energy is high
