You Will Need: 1.Pencil, Text Book Periodic Table 2. Colored Pencils 3. ½ sheet of unlined paper – Bookshelf 4. Electrons and Chemical Bonding- 2 pages-4 sides (Picked up yesterday) 5. Progress Notice - Due today for regular credit and EXTRA credit Due Next Tuesday for regular credit only

1.The substances on the right side of a chemical equation are called this….. 2.What is the only number you can change in a chemical equation to balance it? 3.What substances speed up or help start a chemical reaction? 4.How is an ION different than an atom from an element on the Periodic table? 5.What type of substance slows down or stops a chemical reaction?

6.What do SUBSCRIPTS in an equation tell you? 7.What type of structures to IONIC Bonds form? 8.IONIC Bonds are usually between what two types of elements? 9.Which elements do the Halogens on the periodic table tend to bond with? Why? 10.Where are the NOBLE GASES on the periodic Table? What is their valence? 11.What is the most common form of matter in the universe?

1.Usually between Metals and Nonmetals 2.Transfer of electrons – atoms become IONS 3.Form Crystal lattices 4.Are Brittle 5.High Melting and Boiling points 6.Dissolve Easily in water 7.Form compounds 8.Specific Shape SALT

P = 13+ N = P = 13+ N = Neutral atom because it has equal amounts of plus and minus particles. Positive ION because it has MORE protons than electrons. Page 231

Page 233

Explain: Side One: 1)Why does sodium become an ION? 2)Why does chlorine become and ION? 3) Why do these two elements do this? Side Two: 1)Why is sodium a POSITIVE ION? 2)Why is chlorine a NEGATIVE ION? 3)Why do they bond?

1.Share pairs of electrons 2.More often between Nonmetals 3.Low Melting and Boiling points 4.Free flowing but can be brittle 5.Form molecules 6.Do Not have a specific shape
