For example acids.
The chemical reactivity increase down in the group.
they have the elements and they are in the same substances
Metals, salts, hydroxides
Alkalis are metals, specifically the IA group. So no, they won't react with metals.
All alkali metals (group 1) and most earth-alkali metals (group 2)
They're metals that form alkaline compounds when they react with water.
Among the alkali metals, the tendency to react with other substances increases form top to bottom within the group.Accompanying link shows the reaction from lithium through to cesium
group one and two metals react with oxygen in the air as well as moisture to from metal oxides
Very reactive metals - from group 1 and 2 of the periodic table - can react with water.
Many metals react with oxidizing substances.
The alkali metals in group 1 react by losing one electron.
Most elements will react with at least one other substance. Certain groups of elements have certain substances that they react or don't react with. For Example, Group 1 - Alkali Metals all react vigourously with water. The Inert Gases (exc. Radon) are all highly unreactive and react with a very small amount of substances, if any.
