Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices: (1) Representative elements in the same group of the periodic table have the same number of valence electrons.
(2) Discrete molecules do not exist in ionic compounds.
(3) A sulfate ion has one less oxygen than a sulfite ion.

Question

Quizplus · Accepted Answer

(1) is true since representative elements in the same group have the same number of valence electrons.
(2) is false since ionic compounds do not typically have discrete molecules.
(3) is true since a sulfate ion (SO4 2-) has one less oxygen than a sulfite ion (SO3 2-). Therefore, two of the three statements are true.
