Answer :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and the unpaired electrons present in the molecule.
The given molecule is,
Beryllium has '2' valence electrons and fluorine has '7' valence electrons. Beryllium is the central atom and fluorine is the terminal atom.
Total number valence electrons in = 2 + 2(7) = 16
According to the Lewis-dot structure, there are '4' number of bonding electrons and 12 number of non-bonding electrons (lone-pair).
The Lewis-dot structure is shown below.

The reaction between sodium hydroxide and ammonium sulfate generates ammonia gas along with water and aqueous sodium sulfate. The reaction can be shown as follows:
2NaOH(aq) + (NH4)2SO4(aq) → 2NH3(g) + Na2SO4(aq) + 2H2O(l)
The reaction can be further simplified to give a net ionic equation as:
2Na+(aq) + 2OH-(aq) + 2NH4+(aq) + SO42-(aq) →
2NH3(g) + 2Na+(aq) + SO42-(aq) + 2H2O(l)
Net ionic:
OH-(aq) + NH4+(aq) ↔ NH3(g) + H2O(l)
