6. __________________ When two or more atoms bond by sharing electrons, they form

a molecule.

7. __________________ The elements that have some properties of metals and some

properties of nonmetals are called halogens.

8. __________________ Helium has chemical properties so different from those of the

other elements that it cannot be placed in any group.

9. __________________ Substances that can carry electric current under some

conditions but not under others are called semiconductors.
