You seem to be asking about water.
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Everything tangible is at least one chemical; this includes water. Water is not an element, because it can be decomposed into oxygen and hydrogen by chemical means.
Compound is a substance composed of two or more elements combined in definite proportions, can be broken down by chemical means. Element is a substance that cannot be broken down into simpler substances even by chemical means.
The chemical formula for hydrogen sulphide is H2S. (Compounds have chemical formulas; only chemical elements have chemical symbols.)
Argon (Ar), Hydrogen (H) and uranium (U) are chemical elements. Water (H2O) is a chemical compound.

None are. The elements are not decomposed: the water is. The elements released by the reaction are hydrogen and oxygen.

Chemical Name = Oxygen Chemical Symbol = O There is no chemical formula for elements.

Hydrogen and sulphur are the elements in H2S.
Carbon, hydrogen, and oxygen are the chemical elements in carbohydrates.

Hydrogen and chlorine are chemical elements. They are pure substances because they are made up of only one type of atom. Hydrogen is the simplest element with atomic number 1, while chlorine is a halogen with atomic number 17.
Argon (Ar), Hydrogen (H) and uranium (U) are chemical elements. Water (H2O) is a chemical compound.
