A newly discovered element Bm has 6 valence electrons. How many total valence electrons are in the BmH2 molecule, a molecule that Bm forms with hydrogen?  Draw a valid Lewis Structure for the molecule BmH2 that Bm forms with hydrogen and use the Lewis structure to determine the number of lone pairs of electrons around the central Bm atom in this molecule. What is the formal charge of Bm in BmH2? (Number and sign) What is the hybridization of Bm according to the hybrid orbital model?

A common trait of simple organic compounds is to have Lewis structures where all atoms have a formal charge of zero. Consider the following incomplete Lewis structure for an organic compound called methyl cyanoacrylate, the main ingredient in Super Glue. Draw a complete Lewis structure for methyl cyanoacrylate in which all atoms have a formal charge of zero.

a. How many sticks did you need to make the skeleton structure?____________ b. How many sticks are left over? ____________ If your model is to obey the octet rule, each ball must have four sticks in it except for hydrogen atom balls, which need and can only have one. Each atom in an octet rule species is surrounded by four pairs of electrons. c. How many holes remain to be filled? ____________ Fill them with the remaining sticks, which represent nonbonding electron pairs. Draw the complete Lewis structure for NH2Cl using lines for bonds and pairs of dots for nonbonding electrons.

Write the Lewis structure for nitrosyl fluoride, FNO. Using only a periodic table, identify (a) which is the longer bond. (b) which is the stronger bond. (c) which is the more polar bond.
