What is the average atomic mass of zirconium

Take the weighted average. So this is the final podcast in a series of three where, as you can see, we've already covered some core content and 1 to podcast. This is the 1 to 9 podcast, and it's the third and final part off this podcast Siris for this specific element.

So in this podcast, we're calculating the weight average atomic mass of zirconium. So what we need to do here is take the weighted average where our atomic mass of zirconium is So what we do to calculate this number is we take each isotope mass multiplied by the percentage abundance that has been divided by Then we add all of the numbers together to generate our total atomic mass, which, as I said, is In this example.

Use the following table of abundances and masses of the stable isotopes of z… Based on the relative abundances of each isotope, predict to which isotop… Calculate the number of grams of lithium that contain the same number of ato… View Full Video Already have an account? Charotte M.

Discovery date Discovered by Martin Heinrich Klaproth Origin of the name The name is derived from the Arabic, 'zargun', meaning gold coloured. Allotropes -.

Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. Uses and properties. Image explanation. The Ancient Egyptians used zircon gemstones in jewellery. For the Ancient Egyptians the scarab beetle represented here was a symbol of regeneration and creation, conveying ideas of transformation, renewal and resurrection.

A hard, silvery metal that is very resistant to corrosion. Zirconium does not absorb neutrons, making it an ideal material for use in nuclear power stations. Nuclear reactors can have more than , metres of zirconium alloy tubing. With niobium, zirconium is superconductive at low temperatures and is used to make superconducting magnets. Zirconium metal is protected by a thin oxide layer making it exceptionally resistant to corrosion by acids, alkalis and seawater.

For this reason it is extensively used by the chemical industry. Zirconium IV oxide is used in ultra-strong ceramics. It is used to make crucibles that will withstand heat-shock, furnace linings, foundry bricks, abrasives and by the glass and ceramics industries. It is so strong that even scissors and knives can be made from it.

It is also used in cosmetics, antiperspirants, food packaging and to make microwave filters. Zircon is a natural semi-precious gemstone found in a variety of colours. The most desirable have a golden hue. The element was first discovered in this form, resulting in its name. Cubic zirconia zirconium oxide is a synthetic gemstone.

The colourless stones, when cut, resemble diamonds. Biological role. Zirconium has no known biological role. It has low toxicity. Natural abundance. Zirconium occurs in about 30 mineral species, the major ones being zircon and baddeleyite.

More than 1. Most baddeleyite is mined in Brazil. Zirconium metal is produced commercially by first converting zircon to zirconium chloride, and then reducing the chloride with magnesium. Help text not available for this section currently. Elements and Periodic Table History. Gems that contain zirconium were known in ancient times as zircon. Klaproth failed to isolate the pure metal itself, and Humphry Davy also failed when he tried electrolysis in Totally pure zirconium was only produced in by the Dutch chemists Anton Eduard van Arkel and Jan Hendrik de Boer by the decomposition of zirconium tetraiodide ZrI 4.

These days the metal is produced in bulk by heating zirconium tetrachloride ZrCl 4 with magnesium. Atomic data. Glossary Common oxidation states The oxidation state of an atom is a measure of the degree of oxidation of an atom.

Listen to Zirconium Podcast Transcript :. You're listening to Chemistry in its element brought to you by Chemistry World , the magazine of the Royal Society of Chemistry. Hello and welcome to our tour of the unusual, exciting and deadly aspects of the elements that make up the world around us.

We're kicking off our journey through the Periodic Table with a chemical that sometimes masquerades as diamond but is equally at home in the core of a nuclear reactor or even in an ironworks. To tell the story of this mysterious entity which is otherwise known as zirconium, here's chemist and award winning author John Emsley. Wear it flashing on your finger, or unseen within your frame, it holds the key to nuclear energy, and it's got a gem-like name.

It's zirconium. The name zirconium comes from the Arabic word zargun which refers to a golden-hued gemstone known since Biblical times called zircon. Today artificial gems are made from Zirconium oxide known as cubic zirconia and they sparkle with more brilliance than diamond although they are not as hard. What distinguishes them from real diamond is their higher density of 6.

Zirconium is abundant in S-type stars in which heavier elements are formed by neutron capture. Traces are also present in the Sun. Rock brought back from the moon was found to have a surprisingly high zirconium content.

Down here on Earth zircons has shown that life might have started much earlier than once thought. These were found in Australia in the year were 4. In the Middle Ages colourless gemstones of zircon were thought to be an inferior kind of diamond, but that was shown to be wrong when a German chemist, Martin Klaproth , analysed one in and discovered zirconium.

Klaproth was unable to isolate the metal itself. Today this element is widely used, as zircon, as Zirconium oxide and as the metal itself.
