Hydrogen accepts an electron to form inert gas configuration. In this it resembles :
halogens
alkali metals
chalogens
alkaline earth metals
Hydrogen -
It is the first element in the periodic table. It is lightest element known.
-
Hydride -
Hydrides are binary compounds of the elements with hydrogen. The type of hydrids formed depends upon the electronegativity.
-
Hydrogen accepts an electron to form anion and get inert gas configuration like halogens.
H + e- → H- (hydride ion)
X + e- → X–
halogen halide ion
Therefore, Option(1) is correct.
