Chemical Bonds
Investigation
b. In order to complete its outermost energy level, do you think chlorine will tend to lose all
of its valence electrons or gain one electron? Explain your answer.
Why might these two atoms bond together to form a molecule? In your answer, describe
c.
what you think might happen when sodium and chlorine form a chemical bond.
E
Determining oxidation numbers
An element’s oxidation number is equal to the charge an atom has when it ionizes, that is,
gains or loses electrons.
Use your models of sodium and chlorine to answer the questions below.
a. Remove the valence electron from sodium. What has happened to the balance of positive
and negative charges? What is sodium’s oxidation number?
b. Move the electron you took from sodium into the chlorine. What happens to chlorine’s
charge when it gains the electron from the sodium atom? What is chlorine’s oxidation
number?
