Scandium is element 21, and terbium is element 65.
Some names of rare earth metals are Europium, Terbium, Lutetium, Promethium, Cerium, Scandium, Yttrium, Lanthanum, Praseodymium, Neodymium, Samarium, and Gadolinium.
Terbium has 65 electrons
The original name of scandium is derived from the Latin word "Scandia," which means Scandinavia. Scandium was named after Scandinavia because it was first discovered in rare minerals found in Scandinavia.
The atomic number of terbium (Tb) is 65. This means it has 65 protons in its nucleus. Terbium is a rare earth element and is part of the lanthanide series on the periodic table.
Green trichromatic
Terbium is flammable and burns with a yellowish flame.
The atomic mass of terbium is 158.92
The symbol for the element Terbium is Tb
The element yttrium is found in the transition metal location on the periodic table and is very similar to the lanthanides so it has been grouped with them as a rare earth element.
Scandium has four electronic shells with 2, 8, 9, 2 electrons.
The atomic weight of terbium is 158.93 amu.
Terbium is in the period 6 and is a member of lanthanoids family.
