Question

what is the valency of Ammonia and Ammonium?

Answer 1

Answer:

You need to know the Valency of Ammonia and Ammonium Ion.

Explanation:

Lets first get a clear understanding that Ammonia and Ammonium are just not having the same electron number (Valency). This refers that the total number of electrons present in the outer most orbit of the two (Ammonia and Ammonium) may differ, that is why they have different valencies.

Now you also need to keep in mind that it is the electrons present in the outermost orbit of an atom that decides the number of electrons this compound may loose or gain.

So, when speaking of Ammonia its formula is NH3 and it is a compound. Its valency is 0 as it satisfies Octet rule ( 5 + 3 = 8 electrons in outermost orbit.

Its Oxidation number of is equal to Zero…that means that it may not loose or gain any more electrons as it is very stable compound.

Now speaking of Ammonium ion, it has one nitrogen less, so its valency is +1. It forms a +ve ion or a Cation.
