scandium (SC) was discovered by Lars Fredrick Nilson in 1879. the atomic number is 21, in period 4, classified under metallic(metal), in group 3. it also has a density of 2.99 kg/cm[cubed]. its a silver-white color which devolpes a slightly yellowish or pinkish color when exposed to air.

Is scandium in the human body?
Elemental scandium is not considered to be toxic. Little animal testing of scandium compounds has been done.[29] The median lethal dose (LD50) levels for scandium(III) chloride for rats have been determined and were intraperitoneal 4 mg/kg and oral 755 mg/kg.[30] In the light of these results compounds of scandium should be handled as compounds of moderate toxicity. or you can look up "scandium element" and go to wikipedia hope i helped :D
Is beryllium natural or man-made?
Scandium is a natural chemical element, a solid metal. Some applications are: - alloying component for aluminium - material for X-ray tubes (anticathode) used in X-ray spectrometry - component of some lasers - the oxide is used in high intensity lamps - the iodide is used in halogen lamps - etc.

when you think of soft hair remember SCANDIUM
An element that has some of the characteristics of metal is called?
A metalloid is an element that has some characteristics of both metals and nonmetals. Metalloids are found in a diagonal line between metals and nonmetals on the periodic table, such as silicon and arsenic.
What type of bond does scandium normally form?
Ionic. This is because it is part of the transition metals, which normally combine with nonmetals to form ionic bonds. A metal and a nonmetal form an ionic bond (generally), and two nonmetals tend to form covalent bonds (generally).
Why scandium is not a transition element?
Scandium is considered a transition element because it possesses some of the key characteristics of transition metals, such as the ability to form colored compounds and display variable oxidation states. It is classified as a transition metal due to its partially filled d orbitals and the way it behaves in chemical reactions.
Is scandium non-reactive?
Scandium is a reactive element. It forms compounds with oxygen, halogens, and acids. While it is more stable and resistant to corrosion compared to some other reactive metals, it is not considered non-reactive.
How many electrons are in the scandium valence shell?
The element scandium has 21 electrons. However, most of these occupy the inner orbitals. The only electrons in the valence shell are those in the 2s orbital. Since there are two such electrons, scandium has 2 valence electrons.
What is an element that has some characteristics of metal and some characteristics of a nonmetal?
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.
What is an element that has some characteristics of a metal and some characteristics of an nonmetal?
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.
What is an element that characteristics of a metal and some characteristics of a nonmetal?
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.
What characteristics make a person interesting and unique?
Some characteristics that make a person interesting and unique are the ability to take some risks and curiosity. A good sense of humor and creativity are other characteristics that make someone unique.
What is an element that has some characterists of a metal and some characteristics of a nonmetal?

What is the classification of scandium?
Scandium is used to make high intensity lightbulbs. Scandium is mostly found on the sun and stars. Scandium is a silvery, white, metal. Scandium is used added to mercury vapor lamps so that they will emit light that closely resembles sunlight. Scandium is also added to baseball bats and expensive, sturdy bikes.
