The First Day of School

This is what I learned today:

Q:Why don’t oil and water mix together?
A: Water has a high electric charge, which is positive on one side and negative on the other (this is called polarity), so it follows the ‘opposites attract’ rule, so the positive side of the water molecule attracts itself to (A) the negative side of another water molecule, (B) the negative side of another substance with a high electric charge, or (C) a purely negative substance with a high electric charge, so they (the water and the other substance) mix together. But oil does not have an electric charge (that’s called non-polarity) so it has no reason to mix with the water molecules.

The reason that one side of the water atom is + and one is - is because the water molecule is made up of 2 hydrogen atoms and 1 oxygen atom. The H atoms have 1 proton and 1 electron each, so they are smaller than the O atom, which has 8 protons and 8 electrons. Protons are positively charged, but electrons are negatively charged. When the O atom is by itself, the P’s and E’s cancel each other out, so the O atom has no charge. The same goes for the H atoms; they are both neutral on their own.
So then how do the O atom and the 2 H atoms become polarized when you put them together? Here you go:

The O electrons travel around the P’s (and neutrons, but you don’t really have to worry about those right now) in rings. The O atom has 2 rings; the first one has 2, and the second one has 6, but it wants to have 8, so when you put the 2 H atoms with the O atom, the H atom’s electrons are pulled over to the second ring of the O atom. (Picture this like a mickey mouse, with the ears as H atoms and the head as the O atom) Now there are more E’s than P’s on the O side of the water molecule, so that side is negative. On the H side, there are more P’s than E’s because when the E’s got pulled over to the O atom, the P’s got left behind. (Remember the mickey mouse)
