Which is lightest element




















Jiangxi Ganfeng is the largest lithium metal producer in the world, while its lithium compound capacity ranks third worldwide and first in China. The firm holds lithium resources across Australia, Argentina, and Mexico and has over 4, employees. The smallest atom? If by "biggest" and "smallest", you mean mass which is a measure of how much matter is there , then the smallest is the hydrogen atom with one proton and one electron.

The common name for mercury is quicksilver and was formerly called hydrargyrum which is its Latin name. Mercury is a heavy, slippery d-block element that is liquid at standard conditions for temperature and pressure. Note:Mercury is one of the soft metals.

Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed.

If you touch it, a small amount may pass through your skin , but not usually enough to harm you. What is the lightest element? Asked by: Lucius Daugherty. Which element is known as quicksilver?

Which is the smallest element? Thus, helium is the smallest element, and francium is the largest. What country has most lithium? Are heavier elements rarer? Which element is hardest? Which is the rarest element on earth?

What is the world's most expensive element? What is the first lightest element? Which is lightest gas? The lightest four elements are hydrogen, helium, lithium and beryllium. Hydrogen, helium, lithium and beryllium are the lightest four elements, with one, two, three and four protons, respectively. Hydrogen has no neutrons, helium has two, lithium has four and beryllium has five, and the masses of the elements increase in that order.

You can easily identify the lightest elements by checking the periodic table see Resources. Both of these increase together, so an element with an atomic number of 10 neon is more massive than an element with an atomic number six carbon.

You can always use the periodic table to find the lightest and heaviest elements. Hydrogen is the lightest and most common element in the universe, consisting of just a single proton and a single electron, with the chemical symbol H.

It is colorless and odorless, and exists as a gas at everyday temperatures. However, most of the hydrogen on the Earth is bound up with oxygen as part of water. Hydrogen was originally formed in the big bang and is part of the fusion process that powers stars like our Sun. Helium consists of two protons, two neutrons and two electrons, and has the chemical symbol He.

Like hydrogen, it is a colorless and odorless gas. Lithium contains three protons, four neutrons and three electrons, with the chemical symbol Li. Stage and screen. Birds and the bees. Why can't we build things from it that float?

Michael Anderson, London Lithium is not lighter than oxygen. It is, however, about half as dense as water. So it would float on water if it were not too busy reacting with it, like but not as violently as the related elements sodium and potassium. Tim Green, Bradford, Yorkshire The reason is that lithium is much too reactive and has too low a melting point to be much use in hydraulic engineering. A violent reaction takes place on contact between Lithium and water. The heat of reaction is enough to melt the lithium metal and ignite the hydrogen gas that is produced by the reaction.

The result is a flaming globule of liquid metal scooting around on the surface. When I was at school this was a favourite demonstration during chemistry classes, but we were less safety conscious in those days. Martin Thomas, Farnham, England Carbon also has a lower atomic number than Oxygen, but like Lithium exists as a solid, and is much more dense than Oxygen. Floatation occurs because of buoyancy - the difference in density between two objects.

This is why Archimedes jumped out of the bath, and is the reason why steel ships can float on water. However it is soft, reacts with oxygen and water and is somewhat toxic. It melts at a relatively low temperature. Not a meterial to build a ship.

The next is Beryllium which is physically very good but a deadly poison. Next, Sodium - more reactive than Lithium.
