How do you represent molecules?

Chemical formulas, sometimes also called molecular formulas, are the simplest way of representing molecules. In a chemical formula, we use the elemental symbols from the periodic table to indicate which elements are present, and we use subscripts to indicate how many atoms of each element exist within the molecule.

Answer 2

Three molecule of sodium is represented as 3Na.

• The chemical formula of sodium is Na. It has atomic number 11 and atomic mass 23.
• The number of electrons in sodium is 12.
• It is an alkali metal.
• It resides at group 2 and period II in modern periodic table.
• One molecule of Na is represented as 1Na.
• Thus three molecules of sodium will be represented as 3Na.
