Bonding Definitions

Question 1

Ions of Non-Metals

Answer 1

Gain electrons to fill outer shell (except hydrogen)

Question 2

Ions of Metals

Answer 2

Lose electrons to empty outer shell

Question 3

Polyatomic Ions

Answer 3

Ions made of more than one atom

Question 4

Lewis Dot Diagram

Answer 4

Shows valence electrons

Question 5

Chemical Bonds

Answer 5

Attractive forces that hold atoms and ions together due to sharing or transfer of electrons

Question 6

Ionic Bonds

Answer 6

transfer of valence electrons from metal to non-metal
Forms ions, oppositely charged, so they attract each other to form ionic compounds

Question 7

Ionic Formula

Answer 7

Cation is written first, then anion
Subscript used to represent ratio in compound
Write both ions then swap charges of ions

Question 8

Naming ionic compounds

Answer 8

Metals maintain elemental name
Polyatomic ions maintain name
Last part of non-metal removed and replaced with ‘ide’

Question 9

Covalent Bonds

Answer 9

Sharing of electrons
Electrons split between valence shells, giving each atom something resembling a complete valence shell
Shared electrons count in valence of both atoms
Can be single, double or triple bonds
