The most common isotope of hydrogen has one proton, no neutrons, and one electron. An isotope of hydrogen with 1 neutron would have: an atomic number of 1 and a mass number of 2 In a covalent bond: electrons are shared between atoms so that all atoms have full outer shells A property of a system that is present at one level of organization but absent at the levels below is called: an emergent property An ionic bond is weaker than a covalent bond Modern taxonomy attempts...
