Classification of elements on the basis of electronic configuration
How elements are classified on the basis of electronic configuration?
They are s, p, d and f-block elements. The classification is based on the name of orbitals which receive the last electron. The elements in which the valence shell electron enters the s-orbital are called s-block elements.
What are the 4 types of electron configuration?
The four different types of orbitals (s,p,d, and f) have different shapes, and one orbital can hold a maximum of two electrons. The p, d, and f orbitals have different sublevels, thus can hold more electrons. As stated, the electron configuration of each element is unique to its position on the periodic table.
How many types are the electronic classification of elements?
four types
Solution : All the elements are divided into four types on the basis of their properties and electronic configurations. They are : (i) Noble gas elements (ii) Representative elements (iii) Transition elements and (iv) Inner transition elements.
What is electronic configuration and types of elements?
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 full form of SPDF?
The names of the orbitals s, p, d, and f stand for names given to the groups of lines that are noted originally in the spectra of the alkali metals. These line groups are called the sharp, principal, diffuse, and fundamental. They are the s-orbital, p-orbital, d-orbital, and f-orbital.
What is 1s 2s 2p 3s 3p?
1s 2s 2p 3s 3p represents the electron orbital energy levels.
What do you mean by electronic configuration?
electronic configuration, also called electronic structure or electron configuration, the arrangement of electrons in orbitals around an atomic nucleus.
How many configurations of an element are there?
Notation of Electronic Configuration:

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 |
Why is potassium’s electron configuration 2.8 8.1 and not 2.8 9?
According to octet rule, the outermost shell of an atom can accommodate maximum 8 electrons (except K shell which can accommodate maximum 2 electrons). Hence, the electronic configuration of potassium is 2,8,8,1 and not 2,8,9.
What is the electron configuration of the element?
The electron configuration shows the distribution of electrons into subshells. This list of electron configurations of elements contains all the elements in increasing order of atomic number. To save room, the configurations are in noble gas shorthand.
What are the three rules for writing the electron configurations of elements?
There are three rules for writing electronic configuration: Aufbau principle. Pauli’s exclusion principle. Hund’s Rule.
How do you determine electron configuration?
What is the use of electronic configuration?
Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating with the loss of or gain of electrons in their subsequent orbitals.
Why electronic configuration is important?
A short and simplified answer: The electronic configuration of an atom determines the chemical reactions the atom can participate in, and determines the kinds of molecules that atoms can combine into to form more complicated substances.
