Q. 4.69 - An Introduction to General, Organic, and Biological Chemistry

Question

Fill in the following blanks using higher or lower, more or less: Sr has a _____ionization energy and _______metallic character than Sb.

Step-by-Step Solution

Answer

Sr has a lower ionization energy and more metallic character than Sb.

Step 1: Given Information

We have to find out whether Sr has higher or lower ionization energy than Sb and also if it is more or less metallic than Sb.

Step 2: Explanation

As metallic character decreases in the period and increases down the group while ionization energy increases in the period and decreases down the group. Both Sr and Sb is in $5^{th}$ period but Sr is in group $2^{nd}$ and Sb is in group ${15}^{th}$.

This states that Sr has lower ionization energy than Sb and also it is more metallic than Sb.
