period. However, the electron affinity for Be is less favorable than the electron affinity for Li, as shown below.
Li(g) + e + Li (9) EA = -60 kJ/mol
Be(g) + e + Be (g) EA> 0 kJ/mol
Which of the following best helps to explain why the electron affinity for Be is less favorable than the electron
affinity for Li?

1 Answer

Answer:

Explanation:

Be has a full 2s orbital whereas Li has a paramagnetic orbital; i.e., incomplete orbital which serves to need an electron to fill while Be does not.
