None of the above
|
Detailed explanation-1: -Ammonium ion has the chemical formula of NH4+ having valency of +1 in the form of a positive ion.
Detailed explanation-2: -For (Ammonium ion): Nitrogen left its 1 electron unpaired, so for stabilization, it tends to lose one ion, so its valency is (+1)
Detailed explanation-3: -The valency of ammonium ion is 1.
Detailed explanation-4: -Elements with a valency of 1 can either be metals with 1 valence electron (Li, Na, K, Rb, Cs) or nonmetals with 7 valence electrons (F, Cl, Br, I).
Detailed explanation-5: -The valence electrons of nitrogen (N) are 5 and valence electrons of four hydrogen atoms are four (each hydrogen contains 1 valence electron). There is one positive charge exists on the molecule. Thus, the total number of valence electrons in NH+4 N H 4 + molecule will be, 5+4×1−1=8 5 + 4 × 1 − 1 = 8 .
