Question

What three factors determine the reactivity of an element?

Answer 1

Three factors that determine the reactivity of an element, includes:

* Valence electrons (electrons losing or gaining)
* If the element is a metal or nonmetal
* It's oxidation state
* Electronegativity

Answer 2

1: The number of valence electrons, all elements want eight, so if they have eight, non-reactive, if they have 1 or 7, highly reactive.

2: Type of element, non-metal or metal, noble gas, halogens and alkalis.

3: Lastly the actual overall number of electrons, because that totals to what it has in its shell and what does it do/have.
