Polarity

Question 1

What is electronegativity?

Answer 1

Ability of an atom to attract bonding electrons

Question 2

What happens when an electron pair is further from the nucleus?

Answer 2

Weaker attraction to nucleus

Question 3

True or false: inner electrons shield valence electrons from nucleus attraction.

Answer 3

True

Question 4

What happens when there are more protons in the nucleus?

Answer 4

Greater attraction for electrons

Question 5

What happens to the nuclear pull across a period?

Answer 5

Increases due to more amount of protons

Question 6

What happens to the energy level across a period?

Answer 6

Nothing, no new energy levels
