Explain to the class why Fluorine has very high ionization energy compared to metals.
Fluorine has a smaller size, holding its electrons more tight to the nucleus compared to metals which have a larger size.
Write the name of Si2Br6
disilicon hexabromide
Determine which has higher melting point
HF and HBr
HF because hydrogen forces are stronger than HBr dipole dipole forces
