Mini-Quiz: Types of Chemical Bonding

1. Since Chlorine (Cl) has 7 valance electrons, how would it bond to form a Chlorine molecule (Cl2)?

   It is impossible, because then it would have 14 electrons in its outer shellSorry, not correct. Try another button. It combines with ionic bonding, giving one electron to the other Chlorine atomGood try, but not right. Select another answer. It combines with a single covalent bonding, each sharing 2 valance electronsThat is correct. You sure know the types of chemical bonds.

2. Why is the electron dot notation used to illustrate a molecule?

   It allows you to show all the electrons in each atomSorry, not correct. Try another button. It can be less confusing than drawing the solar system model of the atomsThat is right. You seem quite intelligent. The method is only used to illustrate ionsOops! Wrong answer. Re-read the question and try again.

3. If Potassium (K) has 1 valence electron and Chlorine (Cl) has 7, is KCl possible?

   Yes, by ionic bondingThat is correct. You sure know the types of chemical bonds. No, since they have different number of electronsGood try, but not right. Select another answer. Yes, by double covalent bondingOops! Wrong answer. Re-read the question and try again.
