The electronic configuration of an element is a symbolic notation of the manner in which the electrons of its atoms are distributed over different atomic orbitals.

The positively charged sodium ion will have an electron less than its atomic number, we will remove an electron from the last valence shell of sodium that is 3s1. So the sodium ion will have ten electrons. The electronic configuration of Na+ will be (1s2,2s2,2p6).

[He] 2s2 2p2

A neutral carbon atom has atomic number 6, with 6 protons and 6 electrons. The ground state electron configuration for carbon is 1s22s22p2 .

Lewis Symbols Only the electrons in the valence level are shown using this notation. For example, the Lewis symbol of carbon depicts a “C’ surrounded by 4 valence electrons because carbon has an electron configuration of 1s22s22p2. The Lewis symbol for carbon: Each of the four valence electrons is represented as a dot.

Lone pairs are usually put together. Question : Write Lewis symbols of the these atoms: Lithium (Li), beryllium (Be), boron (B), carbon (C), nitrogen (N), oxygen (O)….Lewis symbol.

Lewis structures (also known as Lewis dot structures or electron dot structures) are diagrams that represent the valence electrons of atoms within a molecule. These Lewis symbols and Lewis structures help visualize the valence electrons of atoms and molecules, whether they exist as lone pairs or within bonds.
