Ammonia, ammonium hydroxide, calcium hydroxide and oxide. I think...
Electrons ruminate around the nucleus in particular circular path known as orbit called shell.
Electronic configuration is the dispense of electrons.
Electronic configuration is also known as electronic structure.
Also termed as spatial methodize.
More than one orbital in the electron shell is known as subshell, they have similar energy level.
In Electronic configuration there are four shell present namely k,l,m,n and there are 4 sub-shell namely s,p,d,f.
As we know that every subshell fills gradually s max 2 electrons p - 6 , d - 10 and f - 14.
So,
According to questions,
Thge element has configuration 1s2 2s2 2p4 hence 8 electrons.

The given reaction is a double replacement reaction; option B.
<h3>What is a chemical reaction?</h3>
A chemical reaction is a reaction in which chemical changes occurs in the atoms of reactants which results in the formation pf products.
The given reaction is as follows:
- Ionic compound + Ionic compound ---> Ionic compound + Ionic compound
Since exchange of ions occur, it is a double replacement reaction.
