Why is europium considered a metal?

It its silvery, malleable, ductile, conducts electricity, and in chemical reactions loses electrons to form positive ions. These are all normal and distinguishing characteristics of metals. read more

Europium in element form satisfies the rule set that classifies it as a metal. And Boy oh Boy, there are whole rule sets about what defines a metal.. Sea of electrons, malleable, what have you. read more

The same reason a metal is defined as a metal. High melting point; Shiny luster surface. Some metals form a dull oxide layer, thus it is shiny under it. Hard/non-brittle and malleable; Electrical conductivity and thermal conductivity; Sometimes possesses magnetic properties; Iron has pretty much all of those properties that define a metal. read more
