The energy of the nucleus keeps the electron inside the atom—just like the Earth keeps the moon in its orbit. Elements that have atomic numbers of up to 92 can be found in nature; those over 92 are created by scientists in a laboratory. In most lighter elements the nucleus of each atom has the same number of protons and neutrons. The atomic mass is never a whole number, because scientists do not just add protons and neutrons together. Atoms that lose electrons become positive ions; atoms that win electrons become negative ions.
In the 1930s and 40s scientists found out that if they bombarded a uranium atom with a neutron the nucleus would split up into two parts. Fission was first used in atomic bombs that the Americans dropped over Japan to end the Second World War.
Compounds can be divided into two groups: organic compounds always have carbon atoms in them. The hydrogen atom is the smallest that we know and it has a very simple structure: one proton with a positive charge and one electron with a negative charge. Hydrocarbons are compounds that only have hydrogen and carbon in them, like petroleum, natural gas or plastic. People who suffer from asthma sometime inhale helium and oxygen because helium can enter the lungs more easily. The industry gets pure iron out of ore that is melted at a high temperature about 1,500 ° C. Chlorine often combines with other elements because it easily accepts free electrons from them. Today, South Africa, the USA and Australia are the world’s largest gold-producing countries.

When diagnosed with 3c 4c 5c 6c bulging discs with severe head pain and pain in your neck radiating into shoulders left arm and tingling in your fingers what all can be done is there a pinched nerve? HOW DO U FIND THE NUMBER OF PROTONS NEUTRONS AND ELECTRONS IN AN ATOMElectron about an isotope. Plutonium is one of the heaviest atoms , about 200 times heavier than hydrogen , which is the lightest element. It is very small if you compare it with the whole atom and it has almost all of an atom’s mass. Each proton carries a positive electrical charge and each electron has a negative electrical charge. Although all atoms of the same element have the same number of protons, they sometimes have more neutrons. In labs scientists can produce radioactivity by bombarding atoms with smaller particles. They are created when two different atoms share the same electron or when electrons travel from one atom to another. Water, for example, is a compound that has two hydrogen atoms and one oxygen atom in it . You can find them in all living creatures, in plants and in a lot of our food, for example sugar and fat. It belongs to the group of noble gases because you cannot combine it with other elements.
Its atomic number is 6 and it has a mass of 12, but there are other isotopes of carbon too. It was one of the first metals discovered and people have been using gold for jewellery and coins for thousands of years. If an atom had a diameter of about 6 km the nucleus would only be as big as a tennis ball.

Sometimes you can find hydrogen isotopes that have two or three neutrons, but they too have only one proton. When you combine two atoms of hydrogen with one atom of oxygen you get a water molecule H 2O. It is used in pencils and, because it is lightweight, you can find it in spaceships, tennis rackets and bicycles.
Dentists use gold to make crowns, because it is easy to shape and gold crowns last a long time. Most of them are used in industry—to cut or polish other objects or as drilling heads in oil fields.
Orthopedists are useless in spine and disk problems as they understand the bone aspects, but not the neurological complexities. Unless you get it looked at and treated, you could wind up with long term nerve damage or worse. I've already faced this and been through it, aside from dealing with these problems myself for over 20 years.
In my case, within 2 weeks of the initial pain my left arm was almost paralyzed, and my fingers were numb from the fingertips to the first knuckle. If you're not taking any anti-inflammatory drugs (which I'd be shocked if you weren't) you need to start.
