What is a subshell electron configuration?
A subshell is a subdivision of electron shells separated by electron orbitals. Subshells are labelled s, p, d, and f in an electron configuration.
What is the standard electron configuration for scandium?
The electronic configuration of scandium is Sc: 1s2 2s2 2p6 3s2 3p6 4s2 3d1 .
How do you write a subshell electron configuration?
Notation
- The electron configuration of an atom is written with the help of subshell labels.
- These labels contain the shell number (given by the principal quantum number), the subshell name (given by the azimuthal quantum number) and the total number of electrons in the subshell in superscript.

What is the subshell electronic configuration of Sulphur?
The electron configuration for sulfur is 1s 2 2s 2 2p 6 3s2 3p4 and can be represented using the orbital diagram below.
How to calculate electron configuration?
If you want to do manually then follow the steps below to write shorthand electron configurations: First, find the required element on the periodic table. Now, find the atomic number of the first noble gas in the periodic table. Write the noble gas symbol in parentheses to start its electronic configuration. Then, continue writing the electron configuration of a certain element until you reach the correct number of electrons.
What is the electronic configuration of scandium?
Scandium has an atomic no. of 21. Therefore electronic configuration of scandium(Sc) is: 1s2 2s2 2p6 3s2 3p6 3d1 4s2. Here, two electrons are in 4s orbital instead of being in 3d orbital because 4s orbital is having lesser energy than 3d orbital and 4s orbital also gives full-filled stability which 3d can not give.
Can two elements have the same electron configuration?
No two elements have the same ground-state electron configuration. note: we differentiate elements by their atomic numbers. each element has a unique atomic number. since atomic number = electron number, each element has a unique electron number.
What is the electron configuration for each element?
The electron configuration of an atom of any element is the of electrons per sublevel of the energy levels of an atom in its ground state.
