Hydrogen

Nonmetal! Exists as H2 (diatomic)

when alone as an element.

Most abundant element in universe…

Rare in Earth’s atmosphere

Alkali Metals Group 1 (1A) Properties of all

metals… Shiny & Good

Conductors Malleable – can be

hammered into thin sheets.

Ductile – can be drawn into thin wires.

Alkali Metals Low density and

melting points. Soft and silver-white

in color Highly unstable

elements that are not found pure in nature.

Alkali Metals

All form +1 ions. Most reactive metals on

table (low ionization energy) and this increases from Li to Fr.

Alkaline Earth Metals

More of a silver-metallic color for this group.

Also highly reactive in nature, but can be stored as an element.

Halogens

Most reactive non-metals on table and increases from I To F.

All form –1 ions. Most form salts by combining with

alkali metals. (+1 ion with –1 ion)
