Question

youve been asked to stabilize a compound whose general state is altered by excess electrons. the element you would add to the compound to most effectively stabilize the compound would be ________. why?

Explanation:

A compound with excess electrons has a net negative charge and needs an electron-accepting (electropositive) element to stabilize it. Alkali metals (e.g., sodium, Na) are highly electropositive, meaning they readily lose their single valence electron. When added, they will donate an electron to neutralize the excess negative charge from the extra electrons in the compound, forming a stable ionic bond and a neutral, stable ionic compound.

Answer:

An alkali metal (e.g., Sodium, Na)
Why? Alkali metals are highly electropositive, readily donating their single valence electron to neutralize the excess electrons in the compound, forming a stable neutral ionic compound.
