Ionic Compounds

Metals tend to

• gain electrons

• lose electrons

nonmetals tend to

• gain electrons

• lose electrons

If an atom gains electrons it

• becomes a positive ion becuase a particle was added to the atom

• remains neutral

• becomes a negative ion based on the charge of an electron

• has no charge because only the number of protons affect the charge of an atom

When metals bond with non-metals they form what type of bonds?

• covalent

• cooperative

• ionic

• lewis

PbS₂

• lead sulfide

• lead II sulfide

• lead sulfur

• lead IV sulfide

AgF

• silver fluoride

• silver fluorine

• monosilver monofluoride

• silver monofluorine

When a nonmetal gains electrons, it becomes this type of ion.

• Anion

• Cation

When a metal loses electrons, it becomes this type of ion.

• Anion

• Cation

The proper formula for magnesium hydroxide:

• MgOH

• Mg(OH)₂

• Mg₂OH

• Mg₂OH₂

Which of the following combinations would need roman numerals in the name?

• potassium + fluorine
