Frequently Asked Questions on Atomic Spectra

1. What are Atomic Spectra?

The spectrum of electromagnetic radiation emitted or absorbed by an electron as it transitions between different energy levels within an atom is known as atomic spectra.

2. In physics and chemistry, What does the term “Spectrum” Mean?

The meaning of spectrum is the same in physics as it is in chemistry. When white light is allowed to flow through a prism, it produces a band of colours on a screen.

3. What do Atoms consist of?

Atoms have an equal number of negative and positive charges. Atoms were described as a spherical cloud of positive charges with embedded electrons in Thomson’s concept.

4. What Is the Number of Spectral Lines?

 When electrons shift from higher energy levels to lower energy levels, spectral lines appear. The following are the two types of spectral lines:

1. Emission lines: Emission lines are a type of spectral line that can appear in a variety of colours and have a black background. Only when the particles emit the wavelength can these lines be seen.
2. Absorption lines are a type of spectral line that can be classified in two ways. These could take the form of dark coloured bands on a black background. When the particles absorb the wavelengths, these lines appear.

5. In the spectrum, How many Spectral Lines may be seen?

When moving from higher to lower energy levels, the spiritual lines can be seen. The concept of numerous spectral lines has been generalised after several research. The elements of the fourth energy level migrate to the third level, and then two second-level elements move to the first level.

6. Mention different series of the spectrum and where the lines fall on the spectrum.

 The many series of the spectrum, as well as the various sections of the spectrum where the lines lie, are shown below:

• The UV band is part of the Lyman Series.
• H alpha line from the Balmer series
• Infrared region of the Paschen Series
• The Brackett Series is an electromagnetic spectrum that exists in the infrared area.
• Infrared region Pfund series
• Infrared region of the Humphreys series.

Atomic Spectra is the spectrum of radiation of electromagnetic waves produced due to the transition of an electron from one energy level to another level within an atom. Atoms have an equal number of negative and positive charges. Atoms were described as spherical clouds of positive charges with embedded electrons in Thomson’s concept. In Rutherford’s model, one tiny nucleus carries the majority of the atom’s mass, as well as its positive charges, and the electrons orbit it.

Every element’s atoms have their own unique spectra and are stable. The spectrum is made up of line spectrums, which are parallel lines that are isolated. In this article, we will learn atomic spectra, its definition, and more in detail.
