The number of valence electrons in the O ²⁻ ion is

Options

  1. A4
  2. B6
  3. C8
  4. D10

Correct answer

C. 8

Step-by-step solution

Number of valence electrons in O with atomic number =8 aligned & K =2 (1 s^2 ) & L =6 (2 s^2 2 p^4 ) aligned In case of O ²⁻ aligned & K =2 (1 s^2 ) & L =8 (2 s^2 2 p^6 ) aligned Hence, valence electrons =8 .
