# How Many Degenerate Orbitals Are Needed To Contain Six Electrons With Two Of Them Unpaired

## What is meant by degenerate energy level?

In quantum mechanics, an energy level is degenerate if it corresponds to two or more different measurable states of a quantum system. Conversely, two or more different states of a quantum mechanical system are said to be degenerate if they give the same value of energy upon measurement.

## What does degenerate mean in chemistry?

Degenerate: Systems (molecules, electrons, orbitals, resonance contributors, etc.) that are of equal energy.

## How many electrons are in 2p orbital?

The second shell has two subshells, s and p, which fill with electrons in that order. The 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons.

## What does it mean for 2 orbitals to be degenerate?

Degenerate orbitals definition:

Electron orbitals having the same energy levels are called degenerate orbitals. As per the Aufbau principle, the lower energy levels are filled before higher energy levels. As per Hund’s rule, degenerate orbitals are filled evenly before electrons are filled into higher energy levels.

## Are 2s and 2p degenerate?

Multi-electron atoms

When an atom only contains a single electron, its orbital energies depend only on the principle quantum numbers: a 2s orbital would be degenerate with a 2p orbital. However, this degeneracy is broken when an atom has more than one electron.

## How many molecular orbitals are formed by combine 2s and 2p?

If the z axis is identified with the internuclear axis, the 2s and 2p_{z} orbitals on each atom all have cylindrical symmetry around the axis and hence may be combined to give σ orbitals. There are four such atomic orbitals, so four σ orbitals can be formed.

## Which atomic orbitals can accommodate a maximum of 6 electrons?

The p sublevel has 3 orbitals, so can contain 6 electrons max.

## Which subshell can accommodate 6 electrons?

Each s subshell holds at most 2 electrons. Each p subshell holds at most 6 electrons.

## How many orbitals are there in 1s does it have degenerate orbitals?

The first shell consists of only s atomic orbital. The second shell consists of s and three degenerate p atomic orbitals and the third shell contains, in addition, five degenerate d atomic orbitals. The fourth and higher shells contain, in addition, seven degenerate f atomic orbitals.

## What is degenerate and non degenerate?

The dimension of the eigenspace corresponding to that eigenvalue is known as its degree of degeneracy, which can be finite or infinite. An eigenvalue is said to be non-degenerate if its eigenspace is one-dimensional.
