Alkali Metals

• Group 1 on the periodic table• One valence electron• Most reactive metals

Alkali Metals

• Group 1 on the periodic table• One valence electron• Most reactive metals• Low melting and boiling points make them soft

Alkali Metals

• Group 1 on the periodic table• One valence electron• Most reactive metals• Low melting and boiling points make them soft• Not found in their pure state in nature

Alkali Metals

• Group 1 on the periodic table• One valence electron• Most reactive metals• Low melting and boiling points make them soft• Not found in their pure state in nature• React with water to form basic (alkaline)

solutions

Noble Gases

• Group 18 on the periodic table• Eight valence electrons (2 for He)• Do not react with other elements unless

forced to• Typically used as a filler gas when space needs

to be taken up without a reaction taking place.
