Question

Compare the first ionization energy of oxygen and sulfur

Answer 1

Which of the following are in the correct order of their ionization energies? (multi-answer question) • O>S>SX− >OX− • F>FX−>ClX−>Cl ..

Answer 2

What is Ionization energy?

Ionisation energy, denoted Eᵢ, is the minimum amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated neutral gaseous atom or molecule

Comparison:

The periodic table of elements Oxygen and Sulfur belong to the same group of elements but sulfur is in period 3 while oxygen is in period 2. Oxygen therefore has a higher ionization energy than sulfur.
