Below are the questions to answer...they are also attached in a pdf document below.
- What do you observe when you move two hydrogen atoms closer together? What happens to the movement of electrons when the atoms are close together? Farther apart?
- Why do you think nonmetals tend to be good at sharing electrons?
- Can metals enter into covalent bonds? Why or why not?
- What determines the bond length of a covalent bond?
- Can one win the "tug of war" during a covalent bond? What might happen one atom did win the “tug of war”?
- How can a piece of wood floating on water illustrate the condition of lowest potential energy and maximum stability?
- Rank single, double and triple bonds in order of increasing strength. How many electrons are shared in each of the bonds?
