Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3. Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63 and an isotopic mass in its nuclear ground state is 62.91367 u. Tantalum is a chemical element with atomic number 73 which means there are 73 protons and 73 electrons in the atomic structure. The chemical symbol for Francium is Fr. Chromium is a steely-grey, lustrous, hard and brittle metal4 which takes a high polish, resists tarnishing, and has a high melting point.

Lead is a heavy metal that is denser than most common materials. Atomic Mass Number – Does it conserve in a nuclear reaction? One atomic mass unit is equal to 1.66 x 10-24 grams. The difference is a measure of the nuclear binding energy which holds the nucleus together. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant. Promethium is one of only two such elements that are followed in the periodic table by elements with stable forms. Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. For 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid. TRUE.
