3 Periodic Table Hydrogen 1 Helium 4 Lithium 7 Beryllium 9 Boron 11 Carbon 12 Nitrogen 14 Oxygen 16 Fluorine 19 Neon 20 Sodium 23 Magnesium 2 4 Aluminum 27 Silicon 28 Phosphorus 31 Chlorine 35 Argon 40 Sulfur 32 Group 1 Group 2Group 13Group 14Group 15Group 16Group 17 Group 18 1 P 0 N 2 P 2 N 3 P 4 N 4 P 5 N 5 P 6 N 6 P 6 N 7 P 7 N 8 P 8 N 9 P 10 N 10 P 10 N 11 P 12 N 12 P 12 N 13 P 14 N 14 P 14 N 15 P 16 N 16 P 16 N 17 P 18 N 18 P 22 N Atomic weight or mass Atomic number

4 Atoms like to have a filled outer shell of electrons. Sometimes, by transferring electrons from one atom to another, electron shells are filled. The atom that gives away an electron will take a positive charge, and the receiving atom will have a negative charge. The charged atoms or ions will be attracted to each other, and form bonds.

5 Some atoms like to share electrons to complete their outer shell. Like this oxygen atom. It needs 2 electrons to follow the 2/8/8 rule. In this case to make water, you would need 2 hydrogen atoms. By sharing electrons the hydrogen atom is also able to complete it’s electron shell. Hydrogen bonds are primarily covalent bonds and a regular covalent bond is very strong. Oxygen

6 On the Inside BY YOURSELF complete BOTH sides of the “On the Inside” worksheet. You do NOT have to draw the Oxygen Atom GO ON

7 Website Click the link below & then click LAUNCH ps07.sci.phys.matter.theatom/the-atom/ Now try this more challenging website & click on ATOM BUILDER ACTIVITY **Hint: Use “The Atom Builder Guide” links at bottom of page for help

8 Interactive Periodic Table Game CLICK ON PICTURE:

9 ___Ductile ___Malleable Able to be pulled into a long wire c d Able to be hammered or rolled into a shape ___Brittleg Easily broken and is not able to be molded or shaped ___ Conductor of electricity k Allows electricity to flow freely

10 ___ Conductor of heat ___Dull Allows heat to flow freely l n Not shiny ___Softm Not hard ___Shiny i Lusterous

11 ___ high boiling point ___ High melting point Boils at a high temp. so is usually a liquid at room temperature h j Melts at high temp. so is usually a solid at room temperature ___ Semiconductor f Will carry electricity only under certain conditions ___Opaque a Not clear or transparent

12 ___Density ___Reactive b e Will quickly & easily combine with other elements D=M÷V, determines is it will sink or float
