Explicação
## Step 1<br />The problem is asking for the properties of alkali metals. Alkali metals are a group of elements in the periodic table, specifically in Group 1, excluding Hydrogen. They are known for their distinctive properties.<br /><br />## Step 2<br />The first option states that alkali metals are non-reactive, firm solids, dull, and do not react with water. This is incorrect because alkali metals are known for their high reactivity, especially with water.<br /><br />## Step 3<br />The second option states that alkali metals are very reactive, soft solids, silvery, and react with water. This is correct. Alkali metals are indeed very reactive, especially with water, and they are soft solids with a silvery appearance.
