Isotopes. : atoms of the same element that have different numbers of neutrons. Two isotopes of an element will have the same atomic number, but different mass numbers (and atomic masses). CARBON (above right). Oxidation and Reduction. Oxidation-reduction (. redox. ) reactions involve transfer of electrons. Oxidation – loss of electrons. Reduction – gain of electrons. Both half-reactions must happen at the same time. SNC2D. Polyatomic Ions. Polyatomic ions are groups of atoms that tend to stay together and carry an overall ionic charge. The ion is typically held together with covalent bonds. The polyatomic ion is capable of bonding with other ions. The Building Blocks of Matter. Chapter 2. Chapter Outline. 2.1 The .
