Determine the number of bonding electrons and the number of nonbonding electrons

Question

Determine the number of bonding electrons and the number of nonbonding electrons in the structure SiO2

Lewis Structures for Covalent Compounds Lewis dot structures show all the valence electrons in an atom or molecule. Lewis dot structures are most often used to show covalent bonding. For example. the dot structure of NF3 is shown in the figure. (figure 1) which shows a total of 26 valence electrons (6 bonding and 20 nonbonding). Part A Determine the number of bonding electrons and the number of nonbonding electrons in the structure of SiO2, Enter the number of bonding electrons followed by the number of nonbonding electrons in the dot structure of this molecule separated by a comma (e.g., 1,2). Part B Draw the main Lewis structure of NOF. Draw nonbonding electrons using the dot notation and bonding electrons as a bond.

Explanation / Answer

There are 4 bonds, each bond has 2 electrons, therefore making it 8 bonding and 8 nonbonding. making it a total of 16 valence electrons.
