Unit 2: Molecular and Ionic Compound Structure and Properties

________ occur when metals of similar radii combine.

The elements are held together by ________ because the positively charged cation is attracted to the negatively charged anion.

________ can sometimes bond because of their empty d- orbital.

When two atoms are too close, the ________ is high, and the nuclei reset each other.

________ never conduct electricity, including pure water.

________ can be made into alloys.

To bond, the cation gives up the electron (s) entirely to the ________.

________ can not conduct as solids because of the electrons stuck in the lattice structure.

________ occur when there are two metals with vastly different radii combine.

________ as solids are held together in a lattice of covalent bonds which makes them very hard, very high melting point and boiling point.
