a. Between As and Bi, the element with the higher ionization energy is

b. Between As and Br, the element with the higher ionization energy is

c. Between S and I, the element with the higher ionization energy is

d. Between S and Sb, the element with the higher ionization energy is


1. Unable to be determined based on periodic properties alone

2. S

3. I

4. Bi

5. Br

6. As

7. Sb

Answer 1

In each pair, the element with the higher ionization energy is Bi, As, I, and S.

Step-by-step explanation:

The element with the higher ionization energy in each pair is:

a. Between As and Bi, the element with the higher ionization energy is Bi.

b. Between As and Br, the element with the higher ionization energy is As.

c. Between S and I, the element with the higher ionization energy is I.

d. Between S and Sb, the element with the higher ionization energy is S.

Ionization energy is the energy required to remove an electron from an atom. It generally increases across a period and decreases down a group in the periodic table. In each pair, the elements with higher ionization energy are those with smaller atomic radius or higher effective nuclear charge.
