Solution

Solution Steps

Step 1: Understanding Ionization Energy Trends

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. The trends in ionization energy across the periodic table are as follows:

Ionization energy generally increases as we move from left to right across a period. This is because the effective nuclear charge increases, making it harder to remove an electron.
Ionization energy generally decreases as we move from top to bottom within a group. This is because the outer electrons are farther from the nucleus and are shielded by inner electrons, making them easier to remove.

Step 2: Analyzing the Options

Let's analyze each option based on the trends:

Option a: "Ionization energy generally decreases as we move left to right and decreases as we move top to bottom in the periodic table." This is incorrect because ionization energy increases from left to right.
Option b: "Ionization energy generally decreases as we move left to right and increases as we move top to bottom in the periodic table." This is incorrect because ionization energy decreases from top to bottom.
Option c: "Ionization energy generally increases as we move left to right and decreases as we move top to bottom in the periodic table." This is correct based on the trends discussed.
Option d: "Ionization energy generally increases as we move left to right and increases as we move top to bottom in the periodic table." This is incorrect because ionization energy decreases from top to bottom.
