Question

Complete the sentences to explain what a similar treatment would predict for the effective nuclear charge on boron valence electrons and whether you would expect the effective nuclear charge to be different for borons 2s electrons compared to its 2p electron. (hint: consider the shape of the 2p orbital compared to that of the 2s orbital.)

Answer 1

The effective nuclear charge on boron's valence electrons would be different for the 2s electrons compared to the 2p electron due to the shape of their orbitals.

Step-by-step explanation:

In boron, the valence electrons are in the 2s and 2p orbitals. Based on the shape of these orbitals, we would predict that the effective nuclear charge on boron's valence electrons would be different for the 2s electrons compared to the 2p electron. The 2s electrons are closer to the nucleus and experience a stronger attractive force, resulting in a higher effective nuclear charge. In contrast, the 2p electron is shielded to some extent by the 2s electrons, leading to a lower effective nuclear charge.

Answer 2

ZcH's electrons = 5-2 = +3.

ZcH for inner electrons = -5 - 0 = +5.

Step-by-step explanation:

Boron 1s² 2s² 2p

As, 2s ⇒ 2.58.

2p ⇒ 2.42.

Electrons = +3.

Greater than 2 cm = 0.35

Slightly greater than +3 .
