Read the false statement. Atoms of elements with one valence electron form anions in order to meet the octet rule. Which answer
Zepler [3.9K]

Answer:

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.
