- Represent the following molecules by Lewis structures: a. CH4 each H atom is bonded to the C atom b. CO2 each O atom is bonded to the C atom c. H2Se each H atom is bonded to the Se atom d. NH3 the H atom is bonded to the N atomarrow_forwardWrite Lewis structures that obey the octet rule (duet rule for H) for each of the following molecules. a. H2CO b. CO2 c. HCN Carbon is the central atom in all of these molecules.arrow_forwardFor each of the following molecular models, write an appropriate Lewis formula.arrow_forward
- 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.arrow_forwardWrite the Lewis symbols of the ions in each of the following ionic compounds and the Lewis symbols of the atom from which they are formed: (a) MgS (b) Al2O3 (c) GaCl3 (d) K2O (e) Li3N (f) KFarrow_forwardUse the simulation (http://openstaxcollege.org/l/16MolecPolarity) to perform the following exercises for a two-atom molecule: (a) Adjust the electronegativity value so the bond dipole is pointing toward B. Then determine what the electronegativity values must be to switch the dipole so that it points toward A. (b) With a partial positive charge on A, turn on the electric field and describe what happens. (c) With a small partial negative charge on A, turn on the electric field and describe what happens. (d) Reset all, and then with a large partial negative charge on A, turn on the electric field and describe what happens.arrow_forward
