Ch. 8 Chemical Bonding

During ionic bonding, electron(s) is/are

• shared between atoms.

• shared between metal and non-metal.

• transferred between atoms.

• transferred from metal to non-metal.

During covalent bonding, electron(s) is/are

• shared between metals.

• shared between metal and non-metal.

• shared between non-metals.

• shared between ions.

A double covalent bond is made up of ....... electrons shared between two atoms.

• 2

• 4

• 8

Atoms go through chemical bonding so as to achieve

• a complete inner electron shell.

• an outer electron shell with 2 electrons.

• an outer electron shell with 8 electrons.
