Barium has a radius (not raduis) which is almost twice as large as that of silicon.

idk if this is an answer but this is what i found in my book. atomic raduis increases down a group and decreases across a period
Uranus is pretty similar to Neptune. They are both ice giants, are roughly the same size, occupy the outer solar system (they are notionally next to each other in 'order') and have significant chemical composition similarities.
The radius (not raduis) of a barium atom is nearly double that of silicon.
Potassium has the larger radius (not raduis!).
Calcium has a larger radius (not raduis) than copper.
Bromine has a larger radius (not raduis) than chlorine.
It is He.
The length of a radius (not raduis) is diameter/2.
The radius (not raduis) is approx 60,268 km.
No, it cannot be a raduis. It cannot be a radius, either.
The radius (not raduis) is 6 inches.
The radius (not raduis) is 1.25 cm.
The radius (not raduis!) is 3.183 cm, approx.
From group 17 (7A), fluorine has the lowest atomic radius.
