2. Area of focus: Copy questions. When we are finished answer them.
What is Ionic Bonding? Explain how it happens?
What is Covalent Bonding? Explain how it happens?
What is Metalic Bonding? Explain how it happens?

3. Chemical bonds: the attraction that holds atoms together as a result of rearranging their electrons.
Atoms try to have 8 valence electrons (or 2 for H and He), so they will either increase their number or decrease it to get closer to 8. This makes them chemically bonded to other atoms.

Ionic – Gain or lose electrons (transfer)
Metallic- Many free electrons

12. Ionization: The process of removing electrons from an atom to form ions.

13. Ionic - One atom strips electron from the other so both are now stable
Ionic - One atom strips electron from the other so both are now stable. Held then by + / - charge

21. Metallic bonding: The bonding between atoms within metals
Metallic bonding: The bonding between atoms within metals. The sharing of many free electrons.

23. Most metal atoms bond with other types of metal to form alloys- a mixture of two or more metals.
Metal atoms lose their valence electrons and become positively charged ions.
The free electrons float around the atoms in a “sea of electrons”. The electrons are attracted to the positively charged atoms.
The” sea of electrons” can explain the malleability, luster, high electrical conductivity, and high thermal conductivity of metals.

25. Remember:
Covalent – Sharing an Electron many of the SPONCH elements.

26. Remember:
Covalent – Sharing an Electron many of the SPONCH elements.
Ionic – Opposite charges + / -

27. Remember:
Covalent – Sharing an Electron many of the SPONCH elements.
Ionic – Opposite charges + / -
Metallic – Many free floating electrons
