Atomic Number Of Scandium

Posted : admin On 1/3/2022

Scandium is the transition metal with the lowest atomic number. The discovery of scandium filled a spot predicted by Mendeleev's periodic table. Scandium took the place of the placeholder element eka-boron. Most scandium compounds have scandium with the Sc 3+ ion. Scandium has an abundance in the Earth's crust of 22 mg/kg (or parts per million). A few important properties of scandium are that the mass number of this element is 44.96 u. Scandium belongs to Group 3, Period 4, and d-block of the periodic table. The atomic structure of scandium consists of 21 protons and 24 neutrons. Scandium also displays properties of electronegativity as it’s a metal.

Origin / Meaning of the name Scandium
Originates from the Latin word Scandia meaning 'Scandinavia'.

Atomic Number of Scandium Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure. The chemical symbol for Scandium is Sc. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Atomic Number of Scandium Atomic Number of Scandium is 21. Chemical symbol for Scandium is Sc. Number of protons in Scandium is 21. Atomic weight of Scandium is 44.955908 u or g/mol. Melting point of Scandium is 1539 °C and its the boiling point is 2832 °C. Naturally occurring scandium (21 Sc) is composed of one stable isotope, 45 Sc. Twenty-five radioisotopes have been characterized, with the most stable being 46 Sc with a half-life of 83.8 days, 47 Sc with a half-life of 3.35 days, and 48 Sc with a half-life of 43.7 hours and 44 Sc with a half-life of 3.97 hours. All the remaining isotopes have half-lives that are less than four hours, and the.

Facts about the History of the Discovery of Scandium Element
Scandium was discovered by Lars Nilson in 1879. Per Teodor Cleve discovered scandium oxide at about the same time as Nilson. In 1869 Dmitri Mendeleev, using his periodic law, predicted its existence and some properties of this element, which he called ekaboron, .
