Answer to Question 1

A

Answer to Question 2

Most economically important metal atoms do not fit easily into the silicate minerals that form most of the crystals in solidifying magma. As a result, fractional crystallization concentrates originally trace quantities of the metal atoms so that they have relatively high concentrations in the last remaining melt. At these high concentrations, the metal atoms typically join with sulfur atoms to make sulfide ore minerals.
