Answer:
Metals are electropositive i.e. they tend to give away their valence electrons to obtain the electric configuration like that of a Noble gas.
Non-metals, on the other hand, are electronegative i.e. they tend to accept electrons to obtain the electric configuration like that of a noble gas.
Boron is metalloid, so is has properties of a metal and non-metal. Boron is not a typical non-metal.
