![]() You will need to refer to a periodic table for proton values. In this notation, the atomic number is not included. Symbol-mass format for the above atom would be written as Cr-52. For instance, the relative atomic mass of zirconium (Zr) is 91.22. This is usually located under the symbol and name of the element. To find an element’s molar mass, start by checking the periodic table for the relative atomic mass of the element. For an example of this notation, look to the chromium atom shown below:Īnother way to refer to a specific atom is to write the mass number of the atom after the name, separated by a hyphen. Molar mass is the mass in grams of 1 mole of any given substance. The "A" value is written as a superscript while the "Z" value is written as a subscript. Both the atomic number and mass are written to the left of the chemical symbol. The composition of any atom can be illustrated with a shorthand notation called A/Z format. Get their names, symbols, atomic numbers, and essential element facts. Meet the first 20 elements of the periodic table. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. ![]() ![]() Element Phosphorus (P), Group 15, Atomic Number 15, p-block, Mass 30.974.

Visualized element properties: Atomic radius, atomic radius graphic, electronegativity (according to Allred-Rochow and Pauling), ionization energy, relative atomic mass, state of matter, ranking list of properties, discovery, classifications. For example, the atomic mass of hydrogen (symbol H) is 1.01 amu (atomic mass units).All important information about the elements: Atomic number, valence electrons, oxidation state, electronegativity according to Allred-Rochow and Pauling, atomic mass, boiling point, melting point, atomic radius, density, history, discoverer, classification, crystalline structure type, electron configuration, basic state, ionization energy, isotopic composition, state of matter, hardness according to Mohs, oxidation numbers, percentage of mass in Earth's crust, year of discovery, half-life, and much more.Access the same amount of information on your browser, faster and deeper than ever before, with the same renowned ease of use.ĭownload now, or access the app directly online, free of charge, and start experimenting. For each element, you must figure out the atomic mass using. With over 4.89 million downloads, our popular PTE app is also available in web format.
