and if its electrical then why isnt everything magnetic and why dont rubber conduct electric if its made of atoms

well i was never good at physics, but i think t-rex hit the spot :)

First the coulumb's law which may help us understand the force of attraction that is developed between electron and the nucleus. But this is based only on the classical theory but one need to apply the quantum theory too. Because, the behaviour of electron may not get classified under the Newtonian theory alone. Usually one gets a question like, "why not the electron bump on the nucleus?" It is possible to imagine that, the electron revolves around the nucleus like the planets around the sun. Further rubber does not conduct because in its molecular structure, there are no free electrons roaming in the conduction band. That is, there is a large forbidden gap between valence band and the conduction band. I know only this much!

Yes, it's electrical attraction.
Not everything is magnetic because the electrons and protons generally cancel each other out. The poles do not align in most everyday objects.
In the presence of a strong enough magnet, almost any material WILL become magnetic, they can levitate wood, plastic, even a small frog. But it requires the energy of a small city.

To conduct electricity, we need free electrons and that is what differentiates metals from non-metals though all elements are made up of atoms which are made of nuclei (containing protons and neutrons) and surrounded by electrons.
Electrons are bound to the atom by electostatic forces but valence electrons, those that are in the outer shells are loosely bound and can come out easily.

The electrostatic force draws it into the nucleus and its angular velocity wants it to go in a vertical line. The upshot of this is that the electron goes in a orbit

it is an electrostatic force of attraction which keeps the electron in orbit. magnetism is determined by the number of unpaired electrons an atom/molecule has. The greater the number of unpaired electrons the more likely it will be paramagnetic.

an electron is negatively charged
the nucleus has protons which are positively charged
the repusion of electrons between them selves andthe attraction to the protons keeps them in orbit
rubber doesnt have free electrons like metals do
metals have electrons in outer shells than dissociate and float around like a liquid so conduction is easy
rubber doesnt

the centripetal force of attraction between the electrons and the nucleus keeps the electrons in orbit.

electrostatic attraction between the negative electron and the positive protons in the nucleus.

It is not electrical force it is centripetal force which keeps the electron in to orbit. it is same like moon revolving around earth
