Lewis Electron-Dot Structures In a previous chapter, you learned that the valence electrons of an atom can be shown in a simple way with an electron dot diagram. Lewis dot diagrams are used to represent valence electrons in an element. CO2: Each oxygen has 5 electrons, plus the 2 in the single bond, for a total of 7 – not quite enough to complete the octet. Remember that Lewis dot structures are drawn for covalent (molecular) compounds that share electrons. Follow these five simple steps and you’ll be able to figure out the structure of almost any compound. Lewis structures, also known as Lewis dot diagrams, Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDS), are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

It is also known as electron dot structure/ Lewis dot diagram, Lewis dot formulas, Electron dot structure, or Lewis Electron dot structure … Carbon has two double bonds, which means it also has 8 electrons. Hydrogen only needs two outer electrons; Beryllium (Be) only needs 4; Boron (B) and Aluminum (Al) only need 6, and Phosphorus (P) and Sulfur (S) can have more than eight, known as an expanded octet.
