Melting point Covalent radiusHalf of the distance between two atoms within a single covalent bond. Classified as a transition metal, Zinc is a solid at room temperature. The higher the value, the larger risk there is to supply. Here's Brian Clegg. Use of this web site is restricted by this site's license Most common uses: The alloy brass contains copper and anywhere from 20-45% of zinc, depending upon the type of brass. If you wish to use the Images in a manner not permitted by these terms and conditions please contact the Publishing Services Department by email. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state … Elements are organised into blocks by the orbital type in which the outer electrons are found. According to the Jefferson National Linear Accelerator Laboratory, the properties of zinc are: Atomic number (number of protons in the nucleus): 30 ... Atomic weight (average mass … The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. Phase at room temperature: Solid 6. The mass of an atom relative to that of carbon-12. Welcome to "A Visual Interpretation of The Table of Elements", the most striking version of the periodic table on the web. A measure of how difficult it is to compress a substance. First isolated by. But it is usually the German chemist Andreas Marggraf who wins the laurels as 'discoverer' for his 1746 experiment isolating zinc. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The unit of measure for mass is the atomic mass unit (amu). The most common ore of zinc is sphalerite (zinc sulfide) and contains around 60% of zinc . The primary ingredient of this is zinc oxide, which is white - it's small amounts of iron oxide that give it that colour. Weights of atoms and isotopes are from NIST article. The RSC makes no representations whatsoever about the suitability of the information contained in the documents and related graphics published on this Site for any purpose. It's often present in vitamin supplements, though most of us get plenty from meat and eggs. Name: Zinc Symbol: Zn Atomic Number: 30 Atomic Mass: 65.39 amu Melting Point: 419.58 °C (692.73 K, 787.24396 °F) Boiling Point: 907.0 °C (1180.15 K, 1664.6 °F) Number of Protons/Electrons: 30 Number of Neutrons: 35 Classification: Transition Metal Crystal Structure: Hexagonal Density @ 293 K: 7.133 g/cm 3 Color: bluish Atomic Structure For more information on the Visual Elements image see the Uses and properties section below. A higher recycling rate may reduce risk to supply. The unit of measure for mass is the atomic mass unit (amu). In fact electricity's role is surprisingly subtle. Values are given for typical oxidation number and coordination. It’s Elemental - The Periodic Table of Elements. Commercially, zinc is obtained from its ores by concentrating and roasting the ore, then reducing it to zinc by heating with carbon or by electrolysis. It is found in soil and sea water. It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Zn-80 (Zinc, atomic number Z = 30, mass number A = 80). Represented in the periodic table as Zn, zinc is a transition metal, grouped with cadmium and mercury. The minimum energy required to remove an electron from a neutral atom in its ground state. Electron configuration Atomic weight (average mass of the atom): 65.38 4. High = substitution not possible or very difficult. The oxidation state of an atom is a measure of the degree of oxidation of an atom. Zinc is a chemical element with atomic number 30 which means there are 30 protons and 30 electrons in the atomic structure. The coating prevents the object treated from rusting.

Relative atomic mass The atomic number of each element increases by one, reading from left to right. Each allotrope has different physical properties. Zn I Ground State 1s 2 2s 2 2p 6 3s 2 3p 6 3d 1 0 4s 2 1 S 0 Ionization energy 75769.33 cm-1 (9.394199 eV) Ref. This is where the 'galvanic' part of the name comes in.    Name The percentage of an element produced in the top producing country. Zinc, symbol Zn, has a Simple Hexagonal structure and SlateGray color. An East India Company ship which sank off the coast of Sweden in 1745 was carrying a cargo of Chinese zinc and analysis of reclaimed ingots showed them to be almost the pure metal. Atoms of the same element with different numbers of neutrons. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Zinc sulfide is used in making luminous paints, fluorescent lights and x-ray screens. The number of protons in an atom. The mass of an atom relative to that of carbon-12. Most zinc is used to galvanise other metals, such as iron, to prevent rusting. 12. Learn more about the properties and uses of zinc in this article. ; Zinc is the fourth most common metal used today (after iron, aluminum, and copper). Political stability of top reserve holder. This page was created by Yinon Bentor. The temperature at which the solid–liquid phase change occurs. And that's just the start for this versatile oxide. Text © The Royal Society of Chemistry 1999-2011 There aren't many elements with names that are onomatopoeic. Group This week the chemical behind calamine lotion for itchy skin, anti dandruff shampoo for a flaky scalp and underarm deodorant for - well, I think we've probably all stood next to someone whom we wish knew a bit more about the chemistry of zinc. Element Zinc (Zn), Group 12, Atomic Number 30, d-block, Mass 65.38. Commercial use of the Images will be charged at a rate based on the particular use, prices on application. Density is the mass of a substance that would fill 1 cm3 at room temperature. World production is more than 11 million tonnes a year. SM95    Melting Point The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Zinc is a bluish-white, lustrous, diamagnetic metal. agreement. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. Zinc is essential for all living things, forming the active site in over 20 metallo-enzymes. Blocks by the ratio of the element in group 12 ( IIB ) of the distance between two atoms.
