Alkaline earth metals show +1 Oxidation state and their atomic volume ...
Atomic Volume of Alkaline Earth Metals
Alkaline earth metals exhibit a +2 oxidation state, not a +1 oxidation state as mentioned in the question. This +2 oxidation state is the most common oxidation state for alkaline earth metals.
Atomic Volume Trend
- As we move down the group of alkaline earth metals, the atomic volume decreases.
- This decrease in atomic volume down the group can be attributed to the increase in the effective nuclear charge experienced by the outermost electrons.
- The increase in the number of energy levels as we move down the group results in a larger atomic size, but the increase in nuclear charge more than offsets this effect, leading to a decrease in atomic volume.
Therefore, the correct statement is that the atomic volume of alkaline earth metals decreases as we move down the group, not that it is irregular or increases.

Alkaline earth metals show +1 Oxidation state and their atomic volume ...
The alkali metal atom show only +1 Oxidation State, because of their unipositive Ion at the time the stable noble gas configuration. The atomic volume of alkali metals is the highest in its period and goes on increasing down the group from top to bottom.
