Question

Which of the following correctly represents the electron affinity of bromine?

Br2(g) + 2e- → 2Br-(g) ,
Br+(g) + e- → Br(g) ,
Br(g) → Br+(g) + e- ,
Br(g) + e- → Br-(g) ,
Br2(g) + e- → Br-(g)

Answer 1

The correct representation of the electron affinity of bromine is Br(g) + e- → Br-(g). This equation shows the process of adding an electron to a gaseous bromine atom to form a bromide ion.

Step-by-step explanation:

The correct representation of the electron affinity of bromine is:

Br(g) + e- → Br-(g)

This equation shows the process of adding an electron to a gaseous bromine atom to form a bromide ion. In this reaction, energy is released, indicating that Bromine has a negative electron affinity.
