Helium is a very light element that is a gas at normal temperatures. Almost all helium atoms contain 2 protons and 2 neutrons and can be made from protons in nuclear fusion within stars, and in thermonuclear explosions. Helium nuclei are one form of decay of radioactive elements, being released as "alpha particles."
Yes. Current consists of electrons flowing in a circuit.

The Mississippi flows through Memphis.
the Columbia River flows mostly through the stae of Washington

Electrons
atom's are made up of protons, neutrons and electrons. protons are positively charged, electrons are negatively charged, and neutrons have no charge. electrons orbit the the positively charged nucleolus and are held tight in orbit because of the nucleus. electrons farthest from the nucleus are called free electrons, and are free to leave. copper is a good conductor because the free electrons are not strongly attracted to the nucleus. a battery has excessive electrons on on side(neg), and not enough on the other side(pos). connect a copper wire between one side, thorugh a load, and to the other side, and free electrons move from one atom to another, like balls bouncing off each other in one direction, as long as this difference in electrons from one point to another exist. thus we have a current flow.........

moving conduction band electrons
Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
because electrons are the only particles that can move in an atom. so when current flows through a circuit it is really electrons moving
Well, matter is atomic by nature, and probably tiny quantum energy strings. Matter is "electrical" in the sense that the outer shells of elements swap electrons to form compounds with atomic bonds.

Electrons flow through wires that are hooked to a battery. The battery's negative terminal repels the electrons, while the positive terminal attracts them.
The free electrons moves through a relatively short distance.
