## How do ground state and excited state electrons differ?

The main difference between ground state and excited state is that ground state is a state where electrons in a system are in the lowest possible energy levels whereas excited state is any state of the system that has a higher energy than the ground state.

## Is an electron in an excited state more or less stable than an electron in the ground state?

In the ground state, two of the lithium electrons are in the orbital of the first energy level. If a lithium atom absorbs enough energy, one of its electrons can move to an orbital with a higher energy. This configuration is referred to as an excited state. An excited state is less stable than the ground state.

## What happens when an excited electron in an atom moves from the ground state?

An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.

## Can electrons stay in excited state?

When an atom is in an excited state, the electron can drop all the way to the ground state in one go, or stop on the way in an intermediate level. Electrons do not stay in excited states for very long – they soon return to their ground states, emitting a photon with the same energy as the one that was absorbed.

## Can hydrogen be in an excited state?

When hydrogen absorbs a quantity of energy exactly equal to E1, the electron goes from the orbital in the first shell (n = 1) to an orbital in the second shell (n = 2). This hydrogen molecule is in an excited state.

## What is the maximum and minimum wavelength of Lyman series?

The longest and the shortest wavelengths of the Lyman series are 121.6nm and 91.2nm respectively.

## What is the maximum and minimum wavelength of Balmer series?

Hence, Max wavelength is 6568 and min wavelength is 3636.

## What is the minimum wavelength of Brackett series?

The shortest wavelength of the Brackett series of a hydrogen-like atom (atomic number Z) is the same as the shortest wavelength of the Balmer series of hydrogen atom.

## What is maximum and minimum wavelength?

The minimum wavelength is zero, but zero is not a possible wavelength. With a wavelength of zero, the wave could be said not to be a wave. The maximum wavelength is infinity, but infinity is not a possible wavelength. With a wavelength of infinity, the wave could be said not to exist.

λ=1873. 6nm.

## What is Paschen’s first line?

ANSWER↓ Wavelength of the first line of Paschen series is `- (R = 109700 cm^-1`).

## How is Paschen series calculated?

The wavelengths of the Paschen series for hydrogen are given by 1/λ=RH(1/32−1/n2) 1 / λ = R H ( 1 / 3 2 − 1 / n 2 ) , n = 4, 5, 6, . . . (a) Calculate the wavelengths of the first three lines in this series.
