Chapter 4: Q. 4.69 (page 127)

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

Short Answer

Expert verified

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

Step by step solution

01

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.

02

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 5thperiod but Sr is in group 2ndand Sb is in group 15th.

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