PLEASE ANSWER Which has the smallest atomic radius and why?

a
Sodium because the element's nucleus has the greatest positive charge of the four elements; so there is a stronger force of attraction that pulls the electrons closer to the nucleus.
b
Argon because the element's nucleus has the greatest positive charge of the four elements; so there is a stronger force of attraction that pulls the electrons closer to the nucleus.
c
Phosphorus because the element's nucleus has the greatest positive charge of the four elements; so there is a stronger force of attraction that releases the electrons closer to the nucleus.
d
Aluminum because the element's nucleus has the smallest positive charge of the four elements; so there is a stronger force of attraction that pulls the electrons closer to the nucleus

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
