What is electron configuration in periodic table?
What is electron configuration in periodic table?
The electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence.
What is the electronic configuration of 1 to 20 elements?
The electronic configuration of first 30 elements with atomic numbers listed above corresponds to the ground state of the specific elements….Electronic Configuration of First 30 Elements with Atomic Numbers.
Atomic Number | Name of the Element | Electronic Configuration |
---|---|---|
18 | Argon (Ar) | [Ne] 3s2 3p6 |
19 | Potassium (K) | [Ar] 4s1 |
20 | Calcium (Ca) | [Ar] 4s2 |
21 | Scandium (Sc) | [Ar] 3d1 4s2 |
How do electron configurations match up with the organization of the periodic table?
The answer is rather simple, if you understand electron configurations: the shape of the periodic table mimics the filling of the subshells with electrons. The shape of the periodic table mimics the filling of the subshells with electrons. The next two electrons, for Li and Be, would go into the 2s subshell.

What are the main features of the long form of periodic table?
Main Features of the Long Form of the Periodic Table : (1) It shows arrangement of elements based on modern periodic law. (2) There are 18 vertical columns known as groups. (3) There are 7 horizontal rows known as periods.
What are periods 1 2 and 3 on the periodic table?
Starting with simple elements, the first three rows of the periodic table, called Periods 1, 2 and 3, correspond to the n=1, n=2 and n=3 levels. Electron shell configurations of the first 18 elementsThe electron shell configurations of the first 18 elements in the periodic table.
What is the electronic configuration of the first period?
First period It is the shortest period and it contains only two elements (H and He). This period corresponds to filling up of K-shell. Electronic configuration of the elements of this period is 1s1and 1s2
