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) The octet rule is used to determine the number of valence electrons an atom possesses.
(2) The formula for the compound sodium carbonate contains parenthesis.
(3) Group IIA and VIA elements form ions that carry two units of charge.

Question

Quizplus · Accepted Answer

1) False: The octet rule is used to predict how atoms will bond to achieve a stable configuration of 8 valence electrons, not to determine the number of valence electrons an atom possesses. 2) True: The formula for sodium carbonate is Na2(CO3), which contains parentheses around the carbonate ion. 3) False: While Group IIA elements (alkaline earth metals) do form ions with a +2 charge, Group VIA elements (oxygen family) typically form ions with a -2 charge, not both groups forming ions with two units of charge in the same manner.
