Sodium is an alkali metal, found on the leftmost side of the Periodic Table with its compatriots: lithium, potassium, rubidium, cesium and francium. What all of these alkali metals have in common is a single electron in their outermost shell. Atoms share electrons with other atoms in order t...
A cation is an ion with a positive electrical charge. The other half of our dissolved salt is made up of chloride, represented by Cl-. Chloride is an anion, an ion with a negative electrical charge, hence the minus sign after it. ...
