Question 14

How do electrons of an element determine that element's reactivity?

Accepted Answer

If the valence shell has missing electrons it is very reactive to attract or lose more electrons.

Answer

If the valence shell has a full ring of electrons it is very reactive because it needs more.

Answer

If the valence shell has a full shell of electrons it is very reactive because it is already full.

Answer

If the valence shell has missing electrons it is not reactive because it is missing electrons.
