Amber is not a mineral because amber is a hardened resin of specific species of ancient trees which has been fossilized over many years.
hope this helps!
Well, nonmetals have more filled shells, making it harder to remove electrons, AND n<span>onmetals have smaller atoms, while metals have larger atoms and therefore less attraction of the electrons to the nucleus. The nuclear charge increases from left to right across a period and the shielding effect stays the same. So it is more difficult to remove an electron from a nonmetal than an alkali metal. ;3</span>
