Alkali Metals


Alkali Metals

Properties: the alkali metals are in group one of the periodic table.

The alkali metals are soft (you can cut them with a knife) and they have compartively low melting points (they are easy to melt).

Reactions with water

The alkali metals are all in the same group of the periodic table so they all have similar reactions.

They all have one electron in their outer shell,  so when they react, each atom looses one electron to become an ion with a +1 charge.

All the alkali metals react with water to form a metal hydroxide and hydrogen gas.

Metal hydroxide solutions are alkaline.

lithum + water → lithium hydroxde + hydrogen
