What is the electronegativity difference of CaF2?

Oh, dude, the electronegativity difference of CaF2 is around 2.0. It's like when you're trying to figure out who's hogging the remote during movie night - one element just wants to take charge and be all electronegative while the other one's like, "Whatever, man, I'll just chill here." So yeah, CaF2 is rocking a 2.0 electronegativity difference.
