What is the representative particle for a salt, nacl2?

It is a cell, all ions, half Na+, half Cl-

NaCl is the formula unit for the cell.

To determine the representative particle for a salt, such as NaCl2, we need to break down the chemical formula. In this case, "Na" represents sodium, and "Cl2" represents two chlorine atoms bonded together.

The representative particle for a salt is called an "ion." Ions are formed when atoms gain or lose electrons, resulting in a positive or negative charge. In the case of NaCl2, sodium (Na) loses one electron, forming a positive ion denoted as Na+. Chlorine (Cl), on the other hand, gains one electron, forming a negative ion denoted as Cl-. Since there are two chlorine atoms in NaCl2, we have two Cl- ions.

Therefore, the representative particle for NaCl2 is the combination of one Na+ ion and two Cl- ions.
