Electron Configuration: The concept of Electron Configuration is very crucial in the physics as well as in the quantum chemistry. The electron configuration is the distribution of electrons in atomic or molecular orbitals of an atom or molecule. Each atom has a unique Electron Configuration. Each electron in an orbital moves independently in an average field created by all other orbitals, according to electronic configurations. In this article we are going to learn about the Electron Configuration of elements more in detail with Electron Configuration of first 20 elements in the periodic table.

Electron Configuration

In simple words Electron Configuration is the arrangements of electrons in atomic or molecular orbitals of an atom. Atomic electron configurations are represented by a standard notation in which all electron-containing atomic subshells are ordered.Atomic orbitals make up these subshells. S, p, d, and f are the four subshell labels that are employed. Each of these subshells has a maximum number of electrons of 2, 6, 10, and 14 accordingly. The electron configuration of the neon atom, for example, is 1s2 2s2 2p6, which means that the 1s, 2s, and 2p subshells are occupied by 2, 2, and 6 electrons, respectively.

Electron Configuration of Elements

The distribution of electrons in an element’s atomic orbitals is described by the element’s electron configuration. Atomic electron configurations adhere to a standard nomenclature in which all atomic subshells that contain electrons are arranged in a sequence with the number of electrons they each hold expressed in superscript. For instance, sodium’s electron configuration is 1s²2s²2p⁶3s¹.

Electron Configuration of Carbon

The first two electrons will be placed in the 1s orbital when writing the electron configuration for carbon. The following two electrons for C are placed in the 2s orbital because 1s can only accommodate two electrons. The 2p orbital will house the final two electrons. The C electron configuration will therefore be 1s²2s²2p².

Electron Configuration: FAQs

Ques. How do you find electron configuration?

Ans. The electron configuration of an element describes how its electrons are distributed throughout its atomic orbitals. Atomic electron configurations follow a standard nomenclature in which the number of electrons that each atomic subshell has is listed in superscript order after each subshell is placed in a sequence.

Ques. What is the electron configuration 1s2 2s2 2p6?

Ans. The electrical arrangement of neon is 1s2 2s2 2p6. The second element in the class of substances known as noble gases is neon. In their atoms’ outermost shells, there are 8 electrons. Neon’s electronic configuration is 1s2, 2s2, and 2p6.

Ques. What is the electron configuration rule?

Ans. In other words, we adhere to the Aufbau Principle, Pauli-exclusion Principle, and Hund’s Rule, which are the three key rules. In order to determine the electrical configuration of cations, electrons are first removed from the outermost p orbital, then from the s orbital, and finally from the d orbitals.

Ques. What is the meaning of 1s 2s 2p 3s 3p?

Ans. The energy levels of the electronic orbitals are 1s 2s 2p 3s 3p. Due to the fact that one atom can have numerous electronic orbitals, energy levels are classified as particular quantum numbers: 1s 2s 2p 3s 3p 6s 4f 5d 4s 3d 4p 5s 4d 5p 6p 7s 5f 6d 7p. The orbital angular momentum quantum number, indicated by l, can be understood.
