Electronic configuration of scandium: [Ar]3d1.4s2
Scandium has 1 3d electron.
Lithium atoms have three electrons.
1 Electronic configuration of scandium: [Ar]3d1.4s2.
Scandium's atomic number is 21. Therefore, neutral scandium has 21 protons and 21 electrons. Scandium's only stable isotope is 45Sc, which has 45 - 21 = 24 neutrons.
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.

I believe 4s2 is the distinguishing (last) electron
Scandium's atomic number is 21. Therefore, neutral scandium has 21 protons and 21 electrons. Scandium's only stable isotope is 45Sc, which has 45 - 21 = 24 neutrons.
scandium belongs to 3d series and in scandium in addition to 2 electrons in 4s one electron of 3d subshell also takes part in bonding so its valency is three despite of only two electrons in outer shell. remember valency is no. of electrons taking part in bonding
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.
It loses electrons.
Scandium has four electronic shells with 2, 8, 9, 2 electrons.
