Document Summary

Homonuclear: diatomic molecules electrons are shared equally heteronuclear : the electrons in the internuclear region are not typically shared equally concept known as electronegativity (x) was developed by linus pauling. Electronegativity (x) values the greater the difference in electronegativity, the greater the magnitude of partial positive and negative charges will be and, hence, the greater the dipole moment of the bond. Step 1: determine the total number of valence electrons. These will be used to form bonds and lone pairs. Step 2: find the central atom (lowest electronegativity) Step 3: draw a single bond between the central atom and each peripheral atom. Step 4: add lone pairs to each of the peripheral atoms until each peripheral atom has an octet of electrons or until you run out of electrons. Step 5: if electrons remain, then add them as non-bonding electrons to the central atom.
