Read each question carefully and provide your best answer. Show all work for calculations.

1. Which of the following elements would have the highest first ionization energy?

a

Na

b

Mg

c

Al

d

Ne

2. What is the general trend for first ionization energy across a period in the periodic table?

a

Increases from left to right

b

Decreases from left to right

c

Remains constant

d

Varies unpredictably

3. Ionization energy is the minimum energy required to remove one   from a gaseous atom or ion.

4. The shielding effect   the effective nuclear charge experienced by the outermost electrons, leading to a   ionization energy.

5. Elements with a   atomic radius generally have a   ionization energy.

6. The second ionization energy is always greater than the first ionization energy.

T

True

F

False

7. Noble gases have very low ionization energies due to their stable electron configurations.

T

True

F

False

8. Explain why ionization energy generally decreases down a group in the periodic table.

9. How does the electron configuration of an atom influence its ionization energy?

10. Refer to the image below showing a simplified atomic structure. Indicate which electron would require the least amount of energy to remove.
