Answer
a) Substance
and Substance D could be alkali metals.b) The reason for this is that alkali metals are known for their low melting points, and Substance
and Substance D have the lowest melting points among the given metals.
Explanation
## Step 1:In this question, we are asked to identify the metals that could be alkali metals from a given table. Alkali metals are a group of chemical elements from Group 1 of the periodic table. They include lithium, sodium, potassium, rubidium, cesium, and francium. These metals are known for their low melting points.## Step 2:By examining the given table, we can see that the melting points of the metals vary greatly. To identify the alkali metals, we need to look for the metals with the lowest melting points. ## Step 3:Comparing the melting points of the metals, we can see that metals A and D have the lowest melting points, 180
and 64
respectively. These values are in the range of melting points for alkali metals, which are known to have low melting points.
