Construct the Lewis structuremodel for the covalent compound carbon tetrachloride (CCl4) using the following steps.
1) The total number of valence electrons in CCl4 is ____.
2) Write the atomic core for the element that seems most likely to be the central atom in the moleculein the space below. Position the remaining atomic cores around it.
3) Place an electron pair between each of the bonding atoms.
4) After distributing the remaining valence electrons so that the carbon and each chlorine atom has an electron octet, write the lewis structure for CCl4 in the box.
