<span>Neutrons.
The nucleus of an atom contains two kinds of particles, protons and neutrons. The number of protons determines what element the atom is. Atoms that have the same number of protons but different numbers of neutrons are isotopes of the same element.
For example, if two atoms both have 1 proton in their nuclei, but one atom has 0 neutrons and the other has 1 neutron, both atoms are hydrogen but they are different isotopes of hydrogen.</span>

Explanation:
A precipitate of calcium carbonate is formed when an aqueous solution of sodium carbonate reacts with aqueous calcium chloride . Balanced equation of this reaction ,
(↓)
This reaction takes place when both reactants present in aqueous conditions, while calcium chloride precipitate separated from aqueous solution by filtration of an aqueous solution. This filtration of precipitate formed in the reaction left behind the residues aqueous solution .
