-Unlike protons and neutrons, which are made up of quarks, electrons are fundamental particles, like neutrinos, mesons, muons and such.(You can also observe the mass difference) -Electrons are subatomic particle with a negative elementary charge. electrons belong to the first generation of the lepton particle family and are generally thought to be elementary particles because they have no known component or substructure. -The electron has spin and charge. When binding to the atomic nucleus, it also acquires an angular momentum quantum number corresponding to the quantized atomic orbital it occupies. Even if electrons in solids form bands and delocalize from the nuclei, in Mott insulators they retain their three fundamental quantum numbers: spin, charge and orbital.


1-If an atom is broken it causes a nuclear reaction!2-The only magnetic metals are: iron, nickel, cobalt!3-sodium metal in water is highly flammable and can explode if you throw something on it! 4-you can make a fatal rocket out of liquid nitrogen, hot water and a soda bottle!(it can break 3 inches glass!)5-Sound travels 4 times faster in water than it does through air!6-More than 75% of the earth is water!7-The core of mercury is still pure iron even with some of the hottest temperatures!(800 degrees!)8-Humans only sleep 35% of the day while sloths and armadillos sleep 80% of the day!(now that is lazy!)9-there are 206 bones in an adult human body and there are 300 bones in kids bodies!(bones fuse together as you grow and age!)10-Flea's can jump 130 times higher than their own height. In human terms this is equal to a 6ft. person jumping 780 ft. into the air.


This video of science is very scientific and you can try some , actually all of the experimets!!!!!!!!!!!!!!!!!!!!!!!!

-Electricity does not 'exist' on its own, when a wire is connected to +ve and -ve polarity, the change in the potential makes the electrons in the valence shell( of the wire )excited. It is these electrons that tries to move towards the -ve which gives rise to electricity. -Electricity is the movement of the electrons 'of' the wire when there is a change in potential. -Electricity flows through metals due to movement of free electrons.

Watch this video of science!

- TNT the most important military chemical explosive. It is a pale yellow crystalline substance that can be safely melted and cast into charges for artillery shells and bombs(that was my favorite part). TNT is often combined with other explosives. It is made by treating toluene (a chemical obtained from the refining of petroleum or coal tar) with a mixture of nitric and sulfuric acids.(never mess with this… it can kill you!!!) -Dynamite an explosive made by combining nitroglycerin with an absorbent material (such as wood pulp) and other ingredients (such as ammonium nitrate or sodium nitrate). Dynamite is relatively safe to handle and was long the most important explosive for blasting. It has been largely replaced by less expensive and less sensitive materials composed primarily of ammonium nitrate. -A demolition charge is a high explosive used for destructive purposes—in bombs, mines, shells, missiles, and torpedoes. A blasting charge is a high explosive used for such purposes as mining and building roads.(this makes the ground flat for building the road on and could be used as a time bomb)

How are electrons made?

Why does electricity go through metal?
