Three Types of Chemical Bonding Summarized

What types of atoms form ionic bonds?

• 2 metals

• 2 nonmetals

• a metalloid and a nonmetal

• a metal and a nonmetal

When atoms gain electrons they become...

• negatively charged

• neutral

• positively charged

• super charged

How do atoms achieve full outer shells in ionic bonding?

• By sharing electrons.

• By transferring electrons.

• By forming a sea of delocalized electrons.

• By repelling each other.

What is a characteristic property of ionic compounds?

• Low melting points.

• Weak bonds.

• High melting points.

• They are always gases at room temperature.

How many electrons do most nonmetal atoms, like oxygen, need to become stable?

• 4

• 6

• 8

• 18

How do non-metal atoms achieve full outer shells in covalent bonding?

• By transferring electrons.

• By forming ions.

• By sharing electrons.

• By becoming delocalized.

What describes the nature of electrons in metallic bonding?

• They are transferred between atoms.

• They are shared in fixed pairs between two atoms.

• They form a sea of delocalized electrons.

• They remain in their original atomic shells.
