Element Classes - Chemistry

Alkali Metals

Group 1 Metals

Most reactive nonmetals

Only found in compounds (not alone)

Alkaline Earth Metals

Group 2

Less reactive that Alkali Metals

Transition Metals

Groups 3-12

Less reactive

High boiling points, colorful

Good catalysts for efficient chemical reactions

Varying ionic charge (due to e- configuration)

Halogens

Group 17

Elements that exist in various states at Standard Temperature and Pressure (STP) - Ex. Br in liquid, I in solid, F in gas

Also have different colors at STP

Noble Gases

Group 18

Highly unreactive (inert)

Nonmetals in gas state

Filled valence shell/outer shell/octet

Metalloids

Elements that share properties with both metals and nonmetals
