Chemistry 8.1

When two atoms share electrons, a chemical bond is formed.  This type of bond is called:

• covalent bond
• ionic bond
• crystal bond
• polyatomic bond

What type of compound consists of molecules that made of atoms that are covalently bonded?

• ionic
• crystal
• noncovalent
• molecular

Molecular compounds that dissolve in water do not conduct electricity because no ___________________ are present.

• charged ions (particles)
• uncharged ions (particles)
• polar
• nonpolar

Molecular compounds do not conduct electricity because they:

• break up into ions
• do not break up into ions
• do not dissolve in water
• have high melting points

What two types of atoms make a covalent bond?

• 2 Nonmetals
• 1 Nonmetal and 1 Metal
• 2 Metals
• 2 Noble Gases
