A) \[_{8}^{16}O\]
B) \[_{8}^{18}O\]
C) \[_{10}^{18}Ne\]
D) \[_{8}^{16}{{O}^{-}}\]
E) \[_{8}^{16}{{O}^{2-}}\]
Correct Answer: E
Solution :
From the given data, it is clear that the atomic number, Z or number of protons of the species is 8. Number of neutrons is also 8, hence atomic mass is 16. Since, the number of electrons are two more than the number of protons, hence it is a binegative species. Thus, the species is \[_{8}^{16}{{O}^{2-}}\].
