Properties of the PeriodicTable
2
Physical properties of matter are categorized as either Intensive or Extensive:
Intensive - Properties that do not depend on the amount of the matter present. Color Odor Luster - How shiny a substance is. Malleability - The ability of a substance to be beaten into thin sheets. Ductility - The ability of a substance to be drawn into thin wires. Conductivity - The ability of a substance to allow the flow of energy or electricity. Hardness - How easily a substance can be scratched. Melting/Freezing Point - The temperature at which the solid and liquid phases of a substance are in equilibrium at atmospheric pressure. Boiling Point - The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure). Density - The mass of a substance divided by its volume

Extensive - Properties that do depend on the amount of matter present.
Mass - A measurement of the amount of matter in a object (grams). Weight - A measurement of the gravitational force of attraction of the earth acting on an object. Volume - A measurement of the amount of space a substance occupies. Length -a measurement of how long something is

Metals Non-Metals
5
Where are the metals located on the periodic table?
6
Properties of Metals Shiny Conduct heat & electricity
Malleable (bendable) Ductile (can be bent into wires) Mostly solids(exception: Mercury) Located in Groups 1-12 Family names include: Alkali Metals, Alakaline Earth Metals& Transition Metals
7
Where are the nonmetals located on the periodic table?
8
Properties of Non-Metals
Brittle Can be solids, liquids, and are mostly Gases Do not conduct heat & electricity Located in Groups 13-18 Family names include: Halogens & Noble Gases
9
Horizontal rows are called PERIODS
Periodic table Mendeleev The periodic table arranges all the elements in groups according to their properties. Vertical columns are called GROUPS/ Families Horizontal rows are called PERIODS 9
10
History of the Periodic Table
Dimitri Mendeleev – 1869 “Father of the Periodic Table” Arranged the elements based on Density Chemical properties Atomic mass Henry Moseley - Atomic number CURRENTLY ARRANGED IN THIS MANNER
11
React explosively with water
Alkali Metals - Group 1: React explosively with water Cesium Shiny, Silver and Soft Not found in Nature
12
Not as soft as Alkali metals Silver in Color & react mildly in water
Alkaline Earth metals – Group 2 Alkaline Earth metals – Group 2 Not as soft as Alkali metals Barium Silver in Color & react mildly in water
13
Have high Conductivity
Transition Metals – Groups Transition Metals Mercury - liquid Have high Reactivity iRON COPPER ZINC GOLD TITANIUM Have high Conductivity
14
Corrosive & Strong Odor
Halogens (HALIDES) – Group 17 Highly reactive with group 1 Halogens Non- metallic Corrosive & Strong Odor Salt - formers Fluorine
15
Noble (INERT) Gases – Group 18
Colorless Odorless Tasteless Non- Reactive INERT
