Is there a relationship between atomie radius and electronegativity? Why or why not?

Yes

Explanation:

Electronegativity is the tendency for atoms to keep electrons closer to them. So, if the atoms are smaller there, there is a stronger pull on the electrons to keep them closer. So, the larger the atom get, due to electron shielding, it become less electro negative. I hope this help. You might get a better explanation from Khan Academy's video on Electronegativity

A relationship is intuitively expected

Does electronegativity relate to atomic radius? A relationship is intuitively expected between electronegativity and radius: the size of an atom is determined by the distribution of electrons around its nucleus. The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom.

Explanation:

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
