Elements and Compounds

Elements are pure substances that cannot be broken down into simpler substances. They are made of only one type of atom and cannot be altered or changed. Examples of elements include oxygen (O2), carbon (C), and hydrogen (H2). Compounds, on the other hand, are combinations of two or more elements. These chemical combinations can be broken down further into their component parts. Examples of compounds include water (H2O), table salt (NaCl), and methane (CH4).
