![]() ![]() The periodic table lists the atomic mass of carbon as 12. This region is highly concentrated with grey dots. Around the origin is a four lobe shaped region forming an 'X' shape around the origin. Oxidation states or atom charge may be positive, negative or zero. The molar mass of any substance is its atomic mass, molecular mass, or formula mass in grams per mole. 1 Comparison of 3d (gray) and 4s (red) electron clouds for a vanadium atom. ![]() The oxidation state reflects the electrical charge of an atom, assuming it only forms ionic bonds. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties. This printable periodic table with charges is an updated version of the Printable Periodic Table Oxidation States. 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. 1.0 Li lithium 6.94 4 2+ 1.5 Be beryllium 9.01 Atomic number Electronegativity Molar mass (g/mol) Ion charge Atomic Symbol SOLID Name 5 2.0 B boron 10.81 6 2.5 C carbon 12.01 7 3- 3.0 N nitrogen 14.01 8 2- 3.5. \), are alike in that their respective molecules are composed of hydrogen and oxygen atoms. Periodic Chart of the Elements 1 (IA) 18 (VIIIA) 1 1+ 2.1 1- H hydrogen 1.01 2 (IIA). ![]()
