• B. False

Answer 1

The correct option is A

True

Although it largely studies metals, the subject is not restricted to only “metals”. The definition in the previous question includes a peculiar word - “metallic”. Astrophysicists define ‘metallic’ as anything not made up of Helium and Hydrogen.Thus, the metallicity of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium.

Many elements and compounds that are generally classified as non-metals become metallic under high pressures; these are formed as metallic allotropes of non-metals.
