Term
Why are substances with high melting points most likely ionicly bonded? 
Definition
Because they can have network structures, which cause high melting and boiling points.

When they are melted or dissolved in water.
Term
What happens when an ionic compound is dissolved in water?
Definition
It conducts electricity.
Term
What two kinds of atoms form a metallic bond?
Definition

Term
What two kinds of atoms make a covalent bond?
Definition
Two nonmetals.
Term
What kind of bond shares electrons?
Definition
Covalent
Term
What is the difference in a polar and nonpolar covalent bond?
Definition
In a polar bond, atoms are shared unequally, but in a nonpolar bond, they are shared equally.
