Question

Identify the element that can form uninegative ion and can be placed in the same group along with halogens.

• A. Nitrogen (N)
• B. Oxygen (O)
• C. Hydrogen (H)
• D. Carbon (C)

Answer 1

The correct option is C Hydrogen (H)

The element Hydrogen also resembles Halogens as it can form Hydrides meaning, it can form $H^{-}$ ions in NaH, LiH, etc.

Halogens can form such halide ions $(F^{-},C{l}^{-},B{r}^{-},etc.)$ in NaF, NaCl, KBr, etc. So, hydrogen can also be placed in ${17}^{th}$ group along with $F,Cl,Br,I,$ etc. as it exhibits similar properties.
