Atomic Radius of Chemical Elements - Material Properties
WebA rare transition element, scandium was discovered in 1878 by L. Nilson in Scandinavia. It occurs in only trace amounts on earth, though it is much more abundant in the sun and other stars. Although scandium can develop a slightly yellow or pink tinge upon exposure to air, it exists in its standard state as a soft, silvery white metal. WebIn transition elements, there are greater horizontal similarities in the properties in contrast to the main group elements because of similar ns 2 common configuration of the outermost … WebReply 2. 18 years ago. d-block element = an element which has at least one bonding electron in its d shell. e.g scandium and zinc.
