Metals Non-Metals

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

Properties of Non-Metals Can be solids (brittle) and liquids, but are mostly Gases Do not conduct heat & electricity Located in Groups 13-18 Family names include: Halogens & Noble Gases

Where are the nonmetals located on the periodic table?

Where are the metals located on the periodic table?

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 Horizontal rows are called PERIODS 6

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

React explosively with water Alkali Metals - Group 1: 1 valence electron React explosively with water Cesium Shiny, Silver and Soft Not found in Nature

Alkaline Earth metals – Group 2: 2 Valence electrons Not as soft as Alkali metals Barium Silver in Color & react mildly in water, conductive

Have high Conductivity Transition Metals – Groups 3 - 12 Transition Metals Mercury - liquid Have high Reactivity Have high Conductivity

Inner Transition Metals Some Radioactive Silver, silvery-white, or gray metals. Conduct electricity

Corrosive & Strong Odor Halogens (HALIDES) – Group 17 Highly reactive with group 1 7 Valence electrons Halogens Non- metallic Corrosive & Strong Odor Salt - formers Fluorine

Needs Iodine!

Noble (INERT) Gases – Group 18 8 Valence electrons except He which has 2 valence electrons Colorless Odorless Tasteless Non- Reactive INERT

Be Mg Ca Sr Ba Ra
