Question

What property of an atom determines its general reactivity?

Answer 1

i guess fair answer would be number of it's unpaired/paired valance electrons. ionization potential has effects and electronegativity too.

Answer 2

how close the outer shell is to being full, OR empty

for example, Lithium(Li) has one valence electron, and thus is more likely to form an ionic bond with another atom, in order to empty it's outer shell.

Answer 3

The number of electrons in it's outer electron shell

Answer 4

ok thank you all of you, i just don't know who to give a medal too
