Electrons move between different energy levels in an atom. When electrons are in the lowest orbital, otherwise known as the ground state, they eventually progress into the highest orbital, also known as the excited state. When electrons move from the excited state back to the lowest orbital, they emit energy in the form of light that varies in colors, depending on the element. Some of these forms of light may not always be visible to the naked eye.

Can atomic spectra be explained on the basis of quantum mechanics?
Yes, atomic spectra can be explained and understood through quantum mechanics. Quantum mechanics provides a framework to describe the discrete energy levels of electrons in atoms, leading to the observation of specific wavelengths in atomic spectra. The theory helps explain phenomena such as line spectra and transitions between energy levels within an atom.
What particle is responsible for spectra?
Spectra are produced by interaction of electromagnetic radiation with matter, typically atoms or molecules. The particle responsible for spectra is the photon, which carries energy and interacts with electrons in the atoms or molecules to produce the spectral lines observed in both emission and absorption spectra.
Who studied the x-ray spectra of the elements to reveal the ir periodicity?
Henry Moseley studied the x-ray spectra of elements and discovered that the atomic number of an element is the fundamental property that determines its chemical and physical characteristics. This finding led to the modern periodic table being organized based on atomic number rather than atomic mass.
What is the name of the spectrum when elements produce different colors when heated?
The spectrum produced when elements emit different colors when heated is called an emission spectrum. Each element has a unique emission spectrum based on the specific wavelengths of light it emits.
What did Moseley use to reorder the elements of Mendeleev periodic table?
Henry Moseley discovered a relation between X-ray spectra and the atomic number of chemical elements.
How Many types of Infrared Spectra?
There are three main types of infrared spectra: absorption spectra, emission spectra, and reflection spectra. Absorption spectra are produced when a material absorbs infrared energy, emission spectra are produced when a material emits infrared radiation, and reflection spectra result from the reflection of infrared radiation off a material.
What effect does the nucleus have on atomic spectra of different elements?
The nucleus of an atom does not directly affect the atomic spectra of different elements. The atomic spectra are mainly a result of the electron configuration and transitions in the electron energy levels. However, the nucleus can indirectly influence the spectra through its impact on the arrangement and energy levels of the electrons.
How is atomic Spectra helpful to scientist?
Atomic spectra are helpful to scientists because they provide valuable information about the energy levels of atoms, which can be used to identify elements and study their properties. By analyzing the spectra produced when atoms absorb or emit light, scientists can determine the composition of substances, study chemical reactions, and investigate the structure of atoms. This information is crucial for various fields such as chemistry, physics, astronomy, and material science.

Why do atomic spectra show individual lines instead of continuous spectra?
Atomic spectra show individual lines instead of continuous spectra because each line corresponds to a specific energy level transition of electrons within the atom. When electrons move between energy levels, they emit or absorb energy in the form of light at specific wavelengths, creating distinct spectral lines. This results in the observed pattern of individual lines in atomic spectra.
What are the limitations of Thomson?
His model cannot explain atomic spectra or radioactivity.
Which part of the electromagnetic spectrum do the atomic emission spectra show?
Atomic emission spectra show specific wavelengths of light emitted by atoms when electrons transition from higher energy levels to lower ones. These spectra typically lie in the visible and ultraviolet regions of the electromagnetic spectrum.
Can atomic spectra be explained on the basis of quantum mechanics?
Yes, atomic spectra can be explained and understood through quantum mechanics. Quantum mechanics provides a framework to describe the discrete energy levels of electrons in atoms, leading to the observation of specific wavelengths in atomic spectra.

How did Moseley discover the atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
