Unit 2-5 Ions and isotopes

Unit 2-5 Ions and isotopes. Ions: losing or gaining electrons. In an atom, protons (+) are in the center and electrons (-) are on the outside. only electrons can be added or taken away. +. +. +. +. +. this is an atom with 5 electrons and 5 protons the atom is neutral

Electron Arrangement

Electron Arrangement. 2.3 Electron arrangement . Electron Arrangement. The study of the emission of light by atoms and ions is the most effective technique for determining the structure of atoms. Electrons surround the nucleus in specific orbitals or energy levels.

Chemical Reactions 2: Equilibrium & Oxidation-Reduction

Chemical Reactions 2: Equilibrium & Oxidation-Reduction. Redox Reactions. Neutral atoms do not have charge since number of electrons equals number of protons (charge equals zero). Charge is acquired when an atom gains (- charge) or loses (+ charge) electrons (last shell). Redox Reactions.
