Question

Which response includes all of the species listed below that have 5 valence electrons?

O^2-, N, P, C^-, F^-

A) N,P

B) N, P, C^-

C) O^2-, C^-, F^-

D) O^2-

E) P, C^-

Answer 1

Valence electron Atomic number of o=8 Hechonie Canligmátion = 2,16 xalence election = 6 Valence electron of o² = 6+2=8 the electrons outermost present in shell. Atomic number of No7 Electronic Confignation = 215] valence eleton = 5 Aformie number of p=15 Electronic Configuration = 2,8,57 valence elechen = 5 Atomic number of ca 6 Electronic configuration = 2, o Valence electron = 4 Valence elechon of Ć - 4+1=5 Atomic number of Faq Electronie configuration - 2.177 valence election = 7 valence electron of f = 7+1=8 5 Valence electrons are N, P and i The species thad have B) is the option.
