An atoms attraction to electrons
100
This number of bonding sites that hydrogen has.
What is 1?
Double to, or lose 200 pts: What number of electrons will H2 have?

What's the IUPAC (official) name for CaCl2?
A. Calcium dichloride B. Calcium chloride
C. Dichloride calcium D. Chloride calcium

Write the IUPAC (official) name for N3O7.
Trinitrogen Heptoxide

What's the difference between how electrons are shared in a polar vs a nonpolar covalent bond?
Polar covalent bonds have atoms with different electronegativities, so one atom pulls the electrons closer.
In a covalent bond, atoms have similar electronegativities and share their electrons evenly.
