is the outer electron in potassium more or less strongly attracted to the positive nucleus than the outer electron in sodium is?

Less strongly attracted.

Explanation:

Potassium and sodium are both alkali metals. That means that they have the ability to be able to gather more valence electrons. They will both gain a positive particle. The potassium electron is less attracted because of the fact that now the sodium has a positive chargem and the electron has a negative charge.

i wanna say it’s between b and d, leaning more towards b.
