The chemical symbol of barium is Ba. Barium is a chemical element, the atomic number of barium is 56. Barium is a group 2 element; it is the fifth element in group 2 of the periodic table. Barium is an alkali metal compound, it is a silvery and soft metal. Barium is highly reactive and due to this reactivity of barium, it is never found as a free element in nature.
In addition to the symbol of an element, additional details are added to the symbol as superscripts or subscripts. It includes the atomic number, mass number or sometimes the charge on the element.
Hence the correct answer is option (A).
Note: Sometimes a 3 letter symbol is also assigned to a new element which is a temporary symbol for the element. For example, the chemical symbol for unniloctium was Uno which was later changed to Hs after the discovery of hassium.
