Why do all bonds form?

• so the number of protons equals the number of electrons

• so an atom can become unstable

• to fill the outermost energy level

Ionic bonds are between...

In an ionic bond, electrons are ​ (a)   from the ​ (b)   to the ​ (c)   . Ionic bonds are ​ (d)   because of the big difference in electronegativity.

• transferred
• metal
• nonmetal
• strong
• weak
• semimetal
• shared

Ionic bonds are formed by transferring an electron from a ​​ (a)   to a ​ nonmetal.

• metal
• metalloid
• nonmetal

Match the following

• Two or more chemically combined elements

• Compound
