Here's a shorter answer. electron transport chain pumps hydrogen ions out of the the mitochondial matrix. hydrogen ions are H+. If you look at the periodic table, hydrogen has 1 proton and 1 electron. An H+ ion is missing an electron, which makes it basically a proton. Since there are a lot of protons pumped out of the matrix, this creates too many h+ ions in the intermembrane space, creating a proton gradient.
