3. Periodic table
1) 2) 3)
PERIOD: ROWS, have the same number of electron shells, as you move across the shell fills up
GROUP: Colums, have the same number of OUTER MOST ELECTRONS
3) The PT is organized into different areas. In these areas the elements have similar properties.
Alkali metals, Alkali Earth metals: groups 1 and 2
Transition metals: groups 3-12
Semimetals: some elements around groups 13 and 14
Halogens: group 17
Noble gases group 18

6. Bonding (Right) What is a chemical bond?
What is a molecule?
What is a compound?
4) What are the three types of bonds? How are they different?
5) What is a polar molecule?
CHEMICAL BOND: An attraction between atoms, forms a chemical substance
MOLECULE: Atoms of a single element or different element joined together
COMPOUND: one or more molecules joined together
4) IONIC: a transfer of electrons. Breaks down into ions.
COVALENT: a sharing of electrons. Breaks down into molecules
HYDROGEN: the bond between a hydrogen atom and an electronegative atom (O,N, F)
5) POLAR MOLECULE: a molecule with a positive and negative side
