Compare the alkali metals and alkaline earth metals with respect to solubility of hydroxides.

Explanation

To compare the alkali metals and alkaline earth metals with respect to the solubility of their hydroxides, we can follow these steps:

### Step 1: Identify the Groups
- **Alkali Metals**: These are located in Group 1 of the periodic table and include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs).
- **Alkaline Earth Metals**: These are located in Group 2 and include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba).

### Step 2: General Solubility Trend
- Both alkali metals and alkaline earth metals form hydroxides, which are generally soluble in water. However, there is a notable difference in their solubility.
