During the formation of the compound sodium chloride, the correct symbol and charge for each of the ions must be... O Na+1 and Cl-1
O Na+1 and F-1
O Na+1 and Br-1
O Na+1 and O-2

Answer : The correct symbol and charge for each of the ions must be and .

Explanation :

The covalent compound are usually formed when two non-metals react.

Ionic compound are usually formed when a metal reacts with a non-metal.

As we know that the sodium chloride is an ionic compound in which sodium is an alkali metal and has one valence electron and chlorine is a non-metal and has 7 valence electrons.

When sodium atom donates an electron to a chlorine atom then it forms an ionic compound that is sodium chloride (NaCl) and the resulting positive ion and negative ion form a stable ionic compound.

Hence, the correct symbol and charge for each of the ions must be and .
