Sodium atoms form sodium metal, a soft, silvery-white metal that. to balance it will need, one Ca 2+ ion and two OH - ions,ĭeduce the formula for sodium carbonate. Neutral atoms and their associated ions have very different physical and chemical properties. The above image clearly shows you the periodic table with charges labeled on it. When atoms gain electron/s, the negatively charged ion is formed, and when the atoms lose electron/s, the positively charged ion is formed.
