The Periodic Table
3
The Table in General Columns Called groups
Elements in a group have similar chemical and physical properties As you go from top to bottom elements get larger Atoms get larger in size
4
Smallest Element #1 Largest Element #114
5
The Table in General Rows: (Periods) First elements very active solids
Last element non reactive gas
6
Rows: (Periods) Reactive Metallic Solid Non-Reactive Non-Metallic Gas
7
The Table in General Rows: (Periods)
Get less reactive as you move from left to right Atoms become less metallic left to right
8
Rows: (Periods) More Reactive Less Reactive More Metallic
Less Metallic

Three Categories Metals Non-Metals Metalloids
34
Properties of a Metal Physical
superior electric and thermal conductivity high luster High density Malleable- ability to be deformed under stress without cleaving (breaking) Alkali & Alkaline Earth metals are extremely reactive, low density, hardness, and melting points
35
Properties of a Metal Chemical Form positively charged ions
Metals can be easily oxidized. Oxidation is informally known as the process of corrosion Metals can react with acid Some metals, like sodium or calcium will react with water to make a base
36
Metalloids: Draw the step ladder & identify the metalloids (use spots)
Draw in the step ladder and mark the Metalloids.
37
Definition of a Metalloid
Found in the area between the metals and the nonmetals on the Periodic Table Sometimes called semi-metals and have characteristics that are similar to both metals and nonmetals.
38
Non-Metal: Identify the non-metals (use stripes)
Mark the Non-Metals
39
Properties of a Non-Metal
Physical low electrical conductivity brittle when solid Most are solid and gas (Bromine is a liquid) dull Do not conduct heat end electricity well lower melting points and boiling points than metals Chemical Form negatively charged ions
