What happens to an atom of chlorine (Cl) if it gains an electron? Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agent, reacting with many elements in order to complete its outer shell. Electrons in the outer shells that are not filled are called valence electrons. A. 17 7. The names for positive and negative ions are pronounced CAT-eye-ons and ANN-eye-ons, respectively. A chlorine atom has a mass number of 35. Valence only describes connectivity; it does not describe the geometry of molecular compounds, or what are now known to be ionic compounds or giant covalent structures.A line between atoms does not always represent a pair of electrons as it does in Lewis diagrams.. Modern definitions. Hence it has 2 electrons in its inner-most shell, 8 electrons in its second shell and 7 electrons in outer-most shell respectively. The element chlorine (Cl) has 17 protons and 17 electrons. Chlorine 37 contains 17 protons, 17 electrons and 20 neutrons. More info.
