Answer:

  • Br²⁺ (g)  → Br³⁺ (g) + e⁻

Explanation:

1) The first ionization energy is the energy required to release an electron from a gas neutral atom.

Hence, this is the energy required for this process:

  • Br (g)  → B⁺ (g) + e⁻

2) The second ionization energy is the energy required to release an electron from a gas ion with charge 1+.

Hence, this is the energy required for this process:

  • Br⁺ (g)  → B²⁺ (g) + e⁻

3) The third ionization energy is the energy required to release an electron from a gas ion with charge +2.

Hence, this is the energy required for this process:

  • Br²⁺ (g)  → B³⁺ (g) + e⁻
