What can you conclude about the classification of boron?
that boron is a noble gas and has a full valence electron shell, is chemically nonreactive, is colorless, is odorless, and has a high boiling point
that boron is a noble gas and has a full valence electron shell, is chemically nonreactive, is colorless, is odorless, and has a low boiling point
that boron is a nonmetal and is dull and brittle, is a poor conductor of heat and electricity, forms acidic oxides, and forms anions in aqueous solutions
that boron is a metalloid and has properties of both metals and nonmetals—it appears dull but is ductile and forms both basic and acidic oxides
