# What is the eigenfunction for the 1s orbital of H atom?

## What is the eigenfunction for the 1s orbital of H atom?

The wave function for 1s orbital of the hydrogen atom is given by. Ψ1s=2 πe−r/a0. where a0= Radius of first Bohr orbit. r= Distance from the nucleus (Probability of finding the electron varies with respect to it)

## What is the orbital of 1s?

The closest orbital to the nucleus, called the 1s orbital, can hold up to two electrons. This orbital is equivalent to the innermost electron shell of the Bohr model of the atom. It is called the 1s orbital because it is spherical around the nucleus. The 1s orbital is always filled before any other orbital.

What is wave function of atomic orbitals?

It describes the behaviour of an electron in a region of space called an atomic orbital (φ – phi ). Each wavefunction has two parts, the radial part which changes with distance from the nucleus and an angular part whose changes correspond to different shapes.

### Is an orbital a wave function?

Fundamentally, an atomic orbital is a one-electron wave function, even though most electrons do not exist in one-electron atoms, and so the one-electron view is an approximation.

### Which is the orbital function?

Orbital, in chemistry and physics, a mathematical expression, called a wave function, that describes properties characteristic of no more than two electrons in the vicinity of an atomic nucleus or of a system of nuclei as in a molecule.

What is the difference between 1s and 2s orbital?

1s orbital is the closest orbital to the nucleus. 2s orbital is the second closest orbital to the nucleus. Energy of 1s orbital is lower than that of 2s orbital. 2s has comparatively higher energy.

#### What is the major difference between 1s orbital and 2s orbital?

1s and 2s sub-orbitals are nearest to the nucleus. The main difference between 1s and 2s orbitals is the difference of their energy level, which is, 2s orbital is a higher energy level than 1s orbital.
