Answer :
Final answer:
The ability of atoms to hold onto an electron decreases as you go from lithium to potassium. Option (B) is correct.
Explanation:
The ability of atoms to hold onto an electron as you go from lithium to potassium decreases.
Lithium has only one electron in its valence shell, and it easily loses it to form a cation with a 1+ charge. As you move towards potassium, the number of protons increases, making the positive charge of the nucleus stronger.
This makes it more difficult for potassium to hold onto its one valence electron, resulting in it being more likely to donate it and form a cation with a 1+ charge.
Therefore, the correct answer is B) It decreases.
