Alkali Metals Reactions | Reactivity | Group IA Elements
Here, we learn chemistry of alkali metals(group 1 elements) of s block. Occurrence. reactions, physical properties of group 1 elements are discussed in this tutorial.
Usually, group 1 elements of s block are very reactive and exist as compounds. Their only valence is one.

55 | Caesium | Cs |
87 | Francium | Fr |
In room temperature condition, Hydrogen element exists as H2gas and rest of others are solid.
Electron Configuration of alkali metals
Those elements have only one electron in their last shell.

Commonly, we can show it as 1s2 2s22p6.. ns1
Example:
Na - 1s2 2s22p6 3s1
K - 1s2 2s22p6 3s23p6 4s1
Reactions of alkali metals
Alkali metals are very reactive due to existence of only one electron in their last shell.
