  • Lewis Dot Symbol
    A diagram showing an element's symbol surrounded by dots that represent its valence electrons.
  • Valence Electron
    An outermost electron involved in chemical bonding, depicted as a dot in electron dot diagrams.
  • Main Group Element
    An element from groups 1A to 8A whose valence electrons equal its group number.
  • Transition Metal
    An element whose valence electrons are determined by the sum of its s and d electrons.
  • Element Symbol
    A one- or two-letter abbreviation representing the nucleus and core electrons in electron dot diagrams.
  • Core Electron
    An electron not involved in bonding, represented by the element symbol in electron dot diagrams.
  • Group Number
    A number indicating an element's column on the periodic table, matching valence electrons for main group elements.
  • Electron Dot Diagram
    A visual tool identical to Lewis dot symbols, used to display valence electrons around an element.
  • s Electron
    An electron found in the s orbital, contributing to valence electron count in transition metals.
  • d Electron
    An electron located in the d orbital, included in the valence electron total for transition metals.
  • Hydrogen
    A unique element with only one shell, where its single electron serves as both core and valence electron.
  • Helium
    A noble gas with two electrons in one shell, where both electrons are considered core and valence electrons.
  • Nucleus
    The central part of an atom, represented by the element symbol in electron dot diagrams.
