Transcript of Nonpolar Bonds
What is an example of a non-polar bond?
a non-polar bond
A covalent bond in which electrons are shared equally.
What happens to the non- polar bond?

W.A.L.T - Identify non-polar bonds
Essential Question - What are non-polar bonds?
Unlike a polar bond, the atoms being shared in a non- polar bond are all the same, so that means there is no stronger atom to receive a negative charge, and there is no weaker atom to receive a positive charge. This means that the bond is neutral.
As you can see, to have a non-polar you don't necessarily need two of the same atoms, yet can actually combine multiple atoms. For instance, combining 4 hydrogen atoms with 1 carbon is an non-polar bond, for H has 1 valence electron each and C has 4 valence electrons. 4 valence electrons + 4 valence electrons (1 for each H * 4 = 4 valence electrons) = 8 valence electrons. A stable molecule! Each element is sharing an equal amount of valence electrons, therefore each atom would have a neutral charge. Not one atom is losing or gaining electrons, but is combining!
If an atom bonds with its same kind, or with atoms with the same number of valence electrons, the electrons will be shared equally. This bond is equal and has a neutral charge.
QOTD is the same!
The milk and the Dial soap bonding represented a polar bond. Now, the reason towards this is because the milk seemed to have contained less valence electrons than the Dial soap. If you payed attention, the blue soap seemed to have lightened after making contact with the milk, yet the milk had barely changed, other than the fact that blue soap stayed on top of it because it was less dense. The lightening of the soap shows that the milk was pulled into the soap and gave it a lighter shade. White+Blue=Light Blue. So, the soap had more valence electrons and took the milk's valence electrons, because it had less, and wanted to bond.
