Chemical Bonding

Chemical Bonding
2
Forming Bonds

• Atoms can bond to each other and make molecules.
• These bonds are what hold molecules together.
• Bonds form when atoms either give away or share
  electrons.

3
Ionic Bonds

• Ionic bonds form when one atom takes an electron
  from another atom.
• Stable atoms are atoms that have full valence
  shells.
• Unstable atoms are atoms that do not have filled
  valence shells

4
Ionic Compounds

• Usually solid at room temperature.
• Usually high melting and boiling points.
• Usually soluble in water.
• Conduct electricity when melted or when dissolved
  in water. 

5
Covalent Bonds

• Covalent bonds are bonds in which atoms share
  electrons.

6
Covalent Compounds

• Usually liquid or gas at room temperature.
• Usually low melting points and boiling points.
• Usually insoluble in water.
• Do not conduct electricity 

7
Metallic Bonds

• Metallic bonds occur when metal atoms share
  electrons.
• Electrons in the outer shells float together
  loosely and form a sea electrons.
