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 did rutherfords model fail to explain why elements had?

Rutherford's model failed to explain why elements emit light at specific frequencies when heated. This phenomenon, known as atomic emission spectra, was later explained by Niels Bohr's model of the atom which introduced the concept of quantized energy levels in the atom.


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 was Niels Bohr's key hypothesis about the behavior of electrons in atoms that he formulated to explain the discrete pattern of atomic spectra?

Niels Bohr's key hypothesis was that electrons orbit the nucleus in specific energy levels or orbits, and they can only transition between these levels by absorbing or emitting specific amounts of energy. This hypothesis explained the discrete pattern of atomic spectra by linking the spectral lines to the energy differences between electron orbits.


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.

What scientists used atomic spectra to develop a model of the atom?

Scientists such as Niels Bohr and Ernest Rutherford used atomic spectra to develop models of the atom. They were able to study the unique wavelengths of light emitted by atoms and used this information to propose new atomic models that helped explain atomic structure and behavior.

Are there any limitations of Chadwick's atomic model?

Yes, Chadwick's atomic model did not fully explain the properties of the electron cloud or electron behavior within an atom. It also did not delve into the concept of electron energy levels and their relationship to atomic spectra.


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.


What has the author G Herzberg written?

G. Herzberg has written: 'Atomic spectra and atomic structure'


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.


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.


How are different types types of spectra created?

The different types of spectra are created by light shining through a prism, a glowing solid or liquid, or by a compressed/non-compressed glowing glass.

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.
