The most closely related characteristic of barium to its chemical reactivity is its high ionization energy.
Does barium have a high reactivity?
- There are two valence (outermost) electrons in each of their atoms. Barium is in period 5, or row 5, therefore it keeps its valence electrons in its fifth shell but is very quickly oxidized or capable of losing the electrons.
- This explains why barium is so reactive, especially when it comes to electronegative components like oxygen. In a nutshell, the ionization energy decreases with increasing atom size.
- Barium has more energy levels and is larger than strontium because it is on the sixth period while strontium is on the fifth. Barium will therefore have a lower ionization energy.
