QuestionWhat makes sodium ($\mathrm{Na}$) highly reactive? Options: non-metal, 11 protons, atomic mass 22.990, or 1 valence electron?

Studdy Solution
odium (Na) has one valence electron. This means it can easily lose this electron to achieve a stable electron configuration. This makes sodium a highly reactive element.
The characteristic of sodium that is responsible for its reactivity is that it has one valence electron.
