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.
How many electrons does the element SC have?
I believe 4s2 is the distinguishing (last) electron
What is the noble gas electron configuration of scandium?
The noble gas electron configuration of scandium is [Ar] 4s2 3d1. Scandium has 21 electrons, and the noble gas configuration represents the nearest noble gas to scandium, which is argon with 18 electrons.
Why scandium has valency of 3 whereas its outer shell has only two electrons?
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
How to find the arrangement of electrons on the atom scandium?
The electron configuration of scandium (Sc) is [Ar] 3d1 4s2, indicating that it has 21 electrons arranged in the shells 1s2 2s2 2p6 3s2 3p6 3d1 4s2. Scandium has one electron in the 3d orbital and two electrons in the 4s orbital. This configuration follows the principles of the Aufbau principle and the Pauli exclusion principle.
How many protons neutrons and electrons in scandium?
No.of protons of scandium is 21 (ATOMIC NUMBER) ATOMIC NO=no.of proton or electron MASS NO=no of proton+ no.of neutron

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.
How many protons does the scandium have?
21
How to find the arrangement of electrons on the atom scandium?
The electron configuration of scandium (Sc) is [Ar] 3d1 4s2, indicating that it has 21 electrons arranged in the shells 1s2 2s2 2p6 3s2 3p6 3d1 4s2. Scandium has one electron in the 3d orbital and two electrons in the 4s orbital. This configuration follows the principles of the Aufbau principle and the Pauli exclusion principle.
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 is the correct electron configuration for scandium?
The element scandium (atomic number 21) has the electron configuration [Ar] 3d1 4s2 Actually the correct configuration is [Ar] 4s2 3d1 this is because d comes after s in the ladder The ladder goes as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p
How many protons does the element scandium have?
21
How many unpaired electrons in the atom Sc in ground state?
There are three unpaired electrons in the ground state of a scandium atom (Sc). This is because scandium has an atomic number of 21, with an electron configuration of [Ar] 3d^1 4s^2, where the 3d orbital has one unpaired electron.
