As you move from right to left on the periodic table the atomic radius fill in the blank

Consider the elements bromine and chlorine; which elements has a larger ionic radius ?

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.
