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 the 21 element?
The element with the atomic number 21 is Scandium. Scandium is the first transition metal and is in Group 3, Period 4 of the Periodic Table. It has 21 electrons in 4 shells with 2 electrons in the outer shell.
What elements of the periodic table can be combined with the element scandium?
Only a few elements can be chemically combined with scandium. Here are a few examples of chemical reactions involving Scandium;Scandium + Chlorine --> Scandium (III) ChlorideScandium + Nitrogen --> Scandium (III) NitrateScandium + Sulphur --> Scandium (III) SulphideScandium + Oxygen --> Scandium (III) Oxide
How many electrons fill the 3 shell?
In Argon, Potassium and Calcium, the limit is eight, but because of the overlapping energy levels, In everything from Scandium upwards, the limit is eighteen.
What has a higher oxidation state scandium or calcium?
Scandium has a higher oxidation state than calcium. Scandium typically exhibits a +3 oxidation state, while calcium usually shows a +2 oxidation state.
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.
Does scandium have more than one valence shell?
yes
How many electron shell does scandium 21 have?
It has 4 shells.
Why scandium has valency of 3 whereas its outer shell has only two electrons?
Scandium has an atomic number of 21, with two electrons in the first shell and eight in the second shell. The valency of scandium is 3 because it tends to lose its two outer electrons in order to achieve a stable configuration with a full outer shell, leaving it with a +3 charge.
What is the electronic configuration of Sc in shell?
The electron configuration of scandium is: [Ar]3d1.4s2.
What is the noble gas notation of scandium?
The noble gas notation of scandium is [Ar] 3d1 4s2, where [Ar] represents the electron configuration of the noble gas argon. Scandium has 21 electrons, with the electron configuration of [Ar] 3d1 4s2.

What are the elements of scandium?
Scandium is, itself, an element and so there are no elements of scandium.
What color is scandium?
Scandium is silvery-white in color.
What is made when scandium and chlorine combine?
When scandium and chlorine combine, they form scandium(III) chloride, which is a white solid compound.
How does scandium coast?
Scandium does not coast.
