![]() Click on 'Element Atomic Number', 'Element Symbol', 'Element Name' and 'Element Symbol' headers to sort. The information on this site has been compiled from a number of sources.This Symbol table gives the Symbol of all the elements of periodic table. Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. beryllium (Be), formerly (until 1957) glucinium, chemical element, the lightest member of the alkaline-earth metals of Group 2 (IIa) of the periodic table, used in metallurgy as a hardening agent and in many outer space and nuclear applications. How to read an electron configuration chart An atomic symbol consists of three parts represented as: The mass number is the sum of the number of neutrons and protons. Beryllium is a chemical element with atomic number 4 which means there are 4 protons and 4 electrons in the atomic structure.The chemical symbol for Beryllium is Be. How to calculate the number of protons, neutrons and electrons in an atom of an element In addition to the information contained within the Periodic Table of Elements, the following articles may be helpful if you are writing a report about an element or if you are making a model of an atom: The following paper-based activities are available: The following on-line games based on the Periodic Table of Elements are available: This periodic table chart lists elements by name in alphabetical order including the element symbol, atomic number, and Pauling electronegativity value for. can be divided up to vowels and consonats having its atomic symbols a.z. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. Deuterium (or hydrogen-2, symbol 2 H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1).The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus. The symbol for an atom indicates the element via its usual two-letter symbol. The element normally exhibits six allotropes and four oxidation states. The symbol for an atom indicates the element via its usual two-letter symbol, the mass number as a left superscript, the atomic number as a left subscript (. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. For example, the symbol for mercury is Hg. ![]() Download a printable version of the Periodic Table of Elements in PDF format: Some reports suggest that lead was probably one of the first metals to be produced by man, and this is likely so given its worldwide occurrence and its relative. Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. A chemical symbol is an abbreviation that we use to indicate an element or an atom of an element.
