A TM is a metal which loses electrons to form an ion with an incomplete D subshell. 65. Naturally occurring scandium is composed of 1 stable isotope 45 Sc. It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc2O3 oxide on the surface. Sc(21) and Zn(30) are d-block elements, they can't change their oxudatiin state by octet expansion. Scandium Metal Description. The electronic configuration of Sc 3+ is same as argon, that means no unfilled d-orbital left. The transition metal group is called the "d-block" of the periodic table. Rep:? This is to do with the definition of a transition metal (TM). a Transition metal is a element group that is mostly solid in room temp except mercury. Scandium is not particularly rare and can be found in small concentrations in the Earth’s crust. So my question is, which definition is correct, and is Scandium a transition metal or not? Scandium is a silvery metal that is soft and has a density of about three times that of water. Scandium is the transition metal with the lowest atomic number. It is the first transition metals to be discovered in the periodic table. Transition metals belong to the d block, meaning that the d sublevel of electrons is in the process of being filled with up to ten electrons. Scandium Facts: 65-66 | Cost of Scandium. Transition metals are both ductile and malleable, and usually lustrous in appearance. Moving from left to right across the periodic table, the five d orbitals become more filled. Scandiums most stable ion is a Sc3+ ion losing both the electrons in its 4s shell and one electron in it's 3d shell. Scandium is a metal in a group known as the transition metals.
