Explanation:Br2 , bromine, is a diatomic element, or a molecular element is NOT an example of a compound. Because it is made up of just one element, hydrogen gas (H2) is a molecule rather than a compound. Because it is made up of hydrogen (H) and oxygen (O) atoms, water (H2O) ...
Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. The relative amounts of the elements in a particular compound do not change: Every molecule of a particular chemical substance contains a characteristic number of atoms...
