![]() ![]() 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.ĭata for this section been provided by the British Geological Survey.Īn integrated supply risk index from 1 (very low risk) to 10 (very high risk). Where more than one isotope exists, the value given is the abundance weighted average.Ītoms of the same element with different numbers of neutrons. This is approximately the sum of the number of protons and neutrons in the nucleus. The mass of an atom relative to that of carbon-12. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase.ĭensity is the mass of a substance that would fill 1 cm 3 at room temperature. The temperature at which the liquid–gas phase change occurs. The temperature at which the solid–liquid phase change occurs. The arrangements of electrons above the last (closed shell) noble gas. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The atomic number of each element increases by one, reading from left to right.Įlements are organised into blocks by the orbital type in which the outer electrons are found. Members of a group typically have similar properties and electron configurations in their outer shell.Ī horizontal row in the periodic table. This citation format is based on MLA.A vertical column in the periodic table. Also replace URL for the actual url of this page (The stay, ok?). Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. "Atomic Radius of Sodium (Na) [& State, Uses, Discovery. To make your life (and citation) easier just copy & paste the information below into your assignment or essay: That gives credibility to your paper and it is sometimes required in higher education. When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information. How about an incentive to share this post?

Maybe add your school logo, work team or anything else to make your paper look cool?Īlong with basic atom / element information (like Sodium atomic radius and all the other atomic data), it also comes with color coded info about: State (Gas, Liquid or Solid at room temperature), Groups/series details and much more. How a small number of atoms can be joined and form completely different substances.Want to learn more details and data about Sodium (Na)? Check my Elements Comprehensive List.Īre you having trouble understanding the basics of atomic elements? This video will walk you through: Medieval Latin: sodanum, (headache remedy) symbol from Latin natrium, (sodium carbonate). Burns in air with a brilliant white flame. Sixth most abundant element in the earth's crust. Obtained by electrolysis of melted sodium chloride (salt), borax and cryolite. Liquid sodium is sometimes used to cool nuclear reactors. There are few uses for the pure metal, however its compounds are used in medicine, agriculture and photography. In the case of Sodium the atomic radius is 2.23 Å. There are cool facts about Sodium that most don't know about. Note: Learn more about the atomic radius here. Ok, so what is the atomic radius of an atom of Na? All atoms have a (theoretical) atomic radius, even Sodium.
