Tantalum oxide may be used to make a glass with a high index of refraction, with applications including use for camera lenses. It is a rare, grey, heavy, hard but ductile, metal with a high melting point that reacts with HF and fused alkalis. The atomic number of a sodium atom is 11 and its mass number is 23. At high temperatures, tantalum has good 'gettering' ability. The origin of the name comes from the Greek word Tantalos meaning father of Niobe in Greek mythology, (tantalum is closely related to niobium in the periodic table). A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei (i.e., the same atomic number, or Z).[1]. no. This works because neutrons and protons are both very close to 1 AMU, and electrons are very close to 0 AMU. 2 synonyms for Ta: atomic number 73, tantalum.
