What is S Orbital?
A spherically symmetric atomic orbital with angular momentum quantum number l = 0. Each energy level contains one s orbital. The 1s orbital is the lowest energy orbital in hydrogen. S orbitals have no nodal planes through the nucleus and can hold up to 2 electrons.

A spherically symmetric atomic orbital with angular momentum quantum number l = 0. Each energy level contains one s orbital. The 1s orbital is the lowest energy orbital in hydrogen. S orbitals have no nodal planes through the nucleus and can hold up to 2 electrons.
The s orbital concept is fundamental to explaining the electron configurations of elements and periodic trends. Understanding s orbitals is essential for predicting bonding in molecules like H₂ and methane. The s-block elements (Groups 1 and 2) are defined by filling s orbitals.
S orbitals are a theoretical concept with no direct safety implications. Understanding electron configuration helps predict the reactivity of s-block metals, many of which are highly reactive.
The formula or notation for S Orbital is: ψ(1s): spherical; n=1,l=0,ml=0; holds max 2e⁻
