This is what keeps the atom together. Electrons are attracted to the protons of ... Opposite polar ends of molecules attract and hold one molecule to another. Alcohol has one O–H bond which is polar, ...

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...

The discovery of the make-up of the nucleus (protons and neutrons) came much later, and was not made by Rutherford. The nucleus was calculated to be about 1/10,000th the size of the atom.
