Read the false statement. Atoms of elements with one valence electron form anions in order to meet the octet rule. Which answer
choice rewords the false statement so it is true? a. Atoms of elements with three valence electrons do not form ions because they meet the octet rule.
b. Atoms of elements with five to seven valence electrons form cations in order to meet the octet rule.
c. Atoms of elements with five to seven valence electrons form anions in order to meet the octet rule.
d. Atoms of elements with one valence electron gain seven electrons in order to meet the octet rule.
C. Atoms of elements with five to seven valence electrons form anions in order to meet the octet rule.
Explanation:
Atoms of elements gain or lose electron(s) to obey the octet rule by forming cations or anions.
Atoms with 1 to 3 valence electrons lose electrons to form cations in order to attain a stable configuration.
Atoms with 5 to 7 valence electrons gain electron(s) to form anions in order to attain stable configuration.
However, atoms with 8 valence electrons do not require to gain or lose electrons since they an octet configuration.
Atoms of metallic elements such as those in group 1 and 2 lose electron(s) to form cations while atoms of non-metallic elements such as halogens require to gain electron(s) to form anions so as to obey the octet rule.
According to Bohr, the amount of energy needed to move an electron from one zone to another is a fixed, finite amount. ... The electron with its extra packet of energy becomes excited, and promptly moves out of its lower energy level and takes up a position in a higher energy level. This situation is unstable, however.
