Explain in terms of particle arrangement why nacl(aq) is a homogeneous mixture

It is a solution comprising of only a single phase

Explanation:

When salt is dissolved in water, the solid completely dissolves in the water to form an aqueous solution of sodium chloride. This aqueous solution of sodium chloride comprises of only a single phase.

A homogenous mixture is known to comprise of only a single phase. Hence if all the particles of solute dissolves and form a single phase with the solvent, the solution is a homogeneous mixture.

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
