What things contain scandium?
Scandium is used in aluminum-scandium alloys for aerospace industry components and for sports equipment such as bicycle frames, fishing rods, golf iron shafts and baseball bats. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry.

What family is scandium in on the periodic table?
Scandium was found in 1879 by Swedish chemist Lars Nilson (1840-99). It is a transition metal, appearing in Group 3 (IIIB). Scandium is a moderately abundant element.
Are cobalt and scandium in the same group?
Cobalt and Scandium are in the same group. Niobium and Cobalt are in the same group.
Is scandium harmful to humans?
Health effects of scandium Scandium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.
Is scandium a rare-earth?
Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. While named rare earths, they are in fact not that rare and are relatively abundant in the Earth’s crust.
What is Group 3 called?
Group 3 is the first group of transition metals in the periodic table. The group is also called the scandium group or scandium family after its lightest member.
Is Group 4 metal or nonmetal?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf).
Does the human body use scandium?
Scandium has no biological role. Only trace amounts reach the food chain, so the average person’s daily intake is less than 0.1 microgram. Scandium can be a threat to the liver when it accumulates in the human body.
What is Scandium Sc called?
Scandium is a chemical element with the symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element, together with yttrium and the lanthanides.
Is scandium positive or negative?
Scandium is paramagnetic from 0 K (−273 °C, or −460 °F) to its melting point (1,541 °C, or 2,806 °F). It becomes superconducting at −273.1 °C (−459.6 °F) at pressures exceeding 186 kilobars….scandium.

Is scandium rare or common?
How is scandium listed on the periodic table?
In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Scandium is [Ar] 3d1 4s2. Possible oxidation states are +3. Density of Scandium is 2.985g/cm3.
Which is the lightest element in the scandium group?
Although some controversy exists regarding the composition and placement of this group, it is generally agreed among those who study the matter that this group contains the four elements scandium (Sc), yttrium (Y), lutetium (Lu), and lawrencium (Lr). The group is also called the scandium group or scandium family after its lightest member.
Where can I find scandium oxide in the world?
Thortveitite (Scandium silicate) contain 45% scandium in the form of scandium oxide but it is very rare in nature. Scandium is mostly produced as a by-product during the extraction of uranium through mineral davidite which contain around 0.02% scandium oxide. It is mainly mined in China, Kazakhstan, Madagascar, Norway and Russia.
How is scandium like a lanthanide like element?
Scandium properties are similar with yttrium so it is often classified as a lanthanide like element. Its compound mostly exists in +3 oxidation state. Its oxides and hydroxide are amphoteric (ion that can react with both acid and base).
