Question

Which of the following is NOT true of electronegativity?



generally increases as atomic radius decreases within a period


generally decreases as atomic number increases within a period


generally decreases as the principal energy level increases within a group


generally increases as atomic radius decreases within a group

Answer 1

Atomic radius increases as # of shells gets bigger and thats when you go down a group. the electronegativity gets smaller because the electrons aren't as tightly held by the nucleus.

Answer 2

as principle energy level n goes up, in the figure i drew electronegativtiy goes down.
