![]() ![]() ![]() ![]() Hydrogen (H), Oxygen (O), Sodium (Na), Chlorine (Cl), Carbon (C), Iron (Fe), copper (Cu), silver (Ag), and gold (Au) are examples of elements.Įlements are distinguished by their name, symbol, atomic number, melting point, boiling point, density and ionization energies. Water (H2O), Sodium chloride (NaCl), Sodium bicarbonate (NaHCO3) and Hydrochloric acid (HCl) are examples of compounds. Can be classified as metal, non-metal or metalloid. There are about 117 elements that have been observed. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes. Each atom has the same atomic number i.e., the same number of protons in their nucleus.Ī compound can be separated into simpler substances by chemical methods/reactions.Įlements cannot be broken down into simpler substances by chemical reactions.Ī compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound.Ī huge, virtually limitless, number of chemical compounds can be created. Elements that compose the compound are chemically combined.Įlements contain only one type of atom. Comparison chart Compound versus Element comparison chartĪ compound contains atoms of different elements chemically combined together in a fixed ratio.Īn element is a pure chemical substance made of same type of atom.Ĭompounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. ![]()
