A) \[{{M}^{+}}\]
B) \[{{M}^{2+}}\]
C) \[{{M}^{-}}\]
D) \[{{M}^{2-}}\]
Correct Answer: C
Solution :
Atomic mass of element (M) = 19 Atomic number of element (M) = 9 Its ions is represented by\[{{\text{M}}^{-}}\] (Electronic configuration of M\[=n{{s}^{2}}n{{p}^{5}}\]). It will gain one electron to acquire stable configuration.You need to login to perform this action.
