- Lithium (Li), Sodium (Na), and Potassium (K) has one electron in their outermost orbits.
- They belong to group 1 and hence they are Alkali Metals and not alkali earth metal.
- Lithium can form lithium oxide, Sodium forms Sodium oxide and Potassium can form Potassium peroxide in the presence of oxygen.
- They are not Inert elements as they react with other compounds.

One electron in their outermost shell:
- Lithium, Sodium, and Potassium all belong to the alkali metal group in the periodic table.
- They each have one electron in their outermost shell, which makes them highly reactive.
- This outer electron is easily lost, leading to the formation of positively charged ions.
Alkali metals:
- Lithium, Sodium, and Potassium are all classified as alkali metals due to their similar properties.
- They are soft, shiny, highly reactive metals that readily form compounds with other elements.
Reactivity and formation of oxides:
- These elements are highly reactive due to the presence of a single electron in their outer shell.
- When they react with oxygen, they form oxides - Lithium oxide (Li2O), Sodium oxide (Na2O), and Potassium oxide (K2O).
Therefore, the common factor among Lithium, Sodium, and Potassium is that they all have one electron in their outermost shell, leading to their similar reactivity and properties as alkali metals.
