Scandium (Sc)
Scandium is an element with the atomic number 21 and represented by the symbol ' Sc ' in the periodic table. Scandium is mined from one of the rare minerals from Scandinavia. The colour it develops when exposed to air is yellowish or pinkish cast. One of the characteristics of Scandium is it gets tarnished and burned easily if ignited.
Which element has the greatest density at stp?
In this problem, we are given four elements (scandium, selenium, silicon, sodium), and we need to figure out which one has the greatest density. The density ( ρ ) (rho) ( ρ ) is a physical property of a substance, and it is defined as a mass ( m ) (m) ( m ) per unit of volume ( V ) (V) ( V ) .
Scandium in geological systems | Natural History Museum
Scandium is a compatible element in many rock-forming minerals such as pyroxenes, amphiboles and clays, where it substitutes for Al. It is therefore rarely concentrated in geological systems except in unusual pegmatites or residual deposits such as bauxites. A better understanding of the mineral residence and behaviour of scandium in geological ...

Choose the element that has a smaller atomic radius :scandium or selenium
Final answer: Using the periodic table trends in atomic radii, we can determine that the atomic radius of scandium is smaller than selenium because scandium is positioned to the left of selenium on the periodic table.. Explanation: In order to determine which element, scandium or selenium, has a smaller atomic radius, it's essential to …

Efficient Selective Extraction of Scandium from Red Mud
The scandium can be recovered from red mud by direct acid leaching but the extraction yields are generally low, and the leaching efficiency of iron and silicon is higher. Therefore, the highly selective process steps (a combined sulfation-roasting-water leaching process) were studied to extract scandium from red mud, and in order to minimize ...
