Unit 1: Electronegativity Flashcards
What is electronegativity?
A measure of the attraction an atom involved in a bond has for the electrons of the bond
What page are the electronegativity values found on?
page 11
What happens to electronegativity across a period?
It increases
Why does electronegativity increase across a period?
More protons = stronger nuclear charge.
Stronger nuclear charge = more bonding electrons attracted.
More bonding electrons attracted = higher electronegativity.
What happens to electronegativity down a group?
It decreases
Why does electronegativity decrease down a group?
More occupied shells = more shielding.
More shielding = less attraction between bonding electrons.
Less attraction = lower electronegativity
