Question

What does a Lewis structure NOT show? a. nonbonding electrons b. three-dimensional molecular shape c. charges applicable) d. bonding electrons of atoms e. bonding arrangement Which arrangement is in the correct order of decreasing radii? a. Na^+ > Cs^+ > I^-. b. Li^+ > Na^+ > K c. Be > Ba^+ > O^2^- d. As^3- > Br^- K^e. F^- > Mg^+ > Cs Which of the following is quantized? a. the speed of a Formula 1 race car b. your age c. the diameter of a redwood tree d. the number of marbles in a bag e. the trajectory of a baseball hit from home plate

Explanation / Answer

Lewis symbols are the simple notations which represents the valence electrons in an atom.And therefore the molecules represented by the lewis symbols show the following characterstics-

1.nonbonding electrons(lewis structure shows all the electrons not taking part in the bonding)

2.bonding electrons(lewis structure shows all the electrons taking part in the bonding)

3.bonding arrangement of the atoms(it gives number of bonds between atoms)

4.it considers charges possessed by the atoms/molecules

5.lewis dot structures do not represent the actual shape of the molecules(three dimensional molecular shape)

Hence the correct answer is (b)
