What is an atoms spectrum?
when a beam of white light is passed through the vapours or a gas, the element absorbs certain wavelengths, while the rest of wavelengths are passed through it. The spectrum of this radiation is called atomic absorption spectrum.The missing wavelengths appear as dark lines in the spectrum.
Describe what happens to the outermost electron in a sodium atom when the atom is heated and made to give off a line spectrum?
When a sodium atom is heated and gives off a line spectrum, the outermost electron absorbs energy and gets excited to a higher energy level. As the electron returns to its original energy level, it releases this energy in the form of light, creating the characteristic line spectrum of sodium.
Which number associated with an atom is a characteristic property?
Atomic number is a characteristic property of an atom. Each element has its own unique atomic number, which is the number of protons in the nucleus of an atom.
What is the name of the range of colors emitted by a heated atom?
The name of the range of colors emitted by a heated (energized, excited, etc...) atom is called an emission spectrum.
How might the spectrum of an atom appear if its electrons were not restricted to particular energy levels?
If an atom's electrons were not restricted to particular energy levels, its spectrum would likely appear as a continuous spectrum rather than discrete lines. This is because the energy levels of the electrons in the atom contribute to the specific wavelengths of light emitted or absorbed, and without these restrictions, the energy transitions would be continuous, resulting in a continuous spectrum.
An emission spectrum of an atom is produced when its electrons are .?
Releasing Energy
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
Why line spectrum is called finger print spectrum?
It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.

How is the light of an emission spectrum of an element produced?
Basically, energy is emitted when an electron falls from a higher energy level to a lower energy level. Such energy is emitted as electromagnetic waves, which in certain cases can be visible light.
According to Bohr's model of the hydrogen atom how is hydrogen's emission spectrum produced?
In Bohr's model of the hydrogen atom, hydrogen's emission spectrum is produced when electrons jump between different energy levels within the atom. When an electron moves from a higher energy level to a lower one, it releases energy in the form of light, which is observed as distinct spectral lines in the emission spectrum. The energy of the emitted light corresponds to the energy difference between the initial and final energy levels of the electron.
Describe what happens to the outermost electron in a sodium atom when the atom is heated and made to give off a line spectrum?
When a sodium atom is heated and gives off a line spectrum, the outermost electron absorbs energy and gets excited to a higher energy level. As the electron returns to its original energy level, it releases this energy in the form of light, creating the characteristic line spectrum of sodium.
What is the difference between bremsstrahlung and characteristic radiation?
Bremstrahlung is German for "braking radiation." It refers to radiation that is associated with the positive or negative acceleration of charged particles. The energy of the emitted photon equals the loss of kinetic energy of the particle. Characteristic radiation refers to groups of discrete wavelengths characteristic of the emitting element.
Origin of line spectrum?
A line spectrum is produced when electrons in an atom transition between discrete energy levels. When an electron absorbs energy, it can move to a higher energy level; when it falls back to a lower level, it emits energy in the form of light at specific wavelengths. This emission creates a series of distinct lines, each corresponding to a specific transition, resulting in a unique spectral fingerprint for each element. The line spectrum is characteristic of the element and can be used to identify it in various applications, such as spectroscopy.
Which number associated with an atom is a characteristic property?
Atomic number is a characteristic property of an atom. Each element has its own unique atomic number, which is the number of protons in the nucleus of an atom.
What is the total collection of photons emitted by a given atom?
The total collection of photons emitted by a given atom is known as its emission spectrum. This spectrum consists of photons with specific energies corresponding to transitions between different energy levels of the atom. The emission spectrum is unique to each element and can be used to identify elements based on the pattern of emitted photons.
What is the difference between the characteristic and bremsstrahlung radiation in terms of their properties and effects?
Characteristic radiation and bremsstrahlung radiation are two types of X-ray emissions produced in different ways. Characteristic radiation is emitted when an electron transitions from a higher energy level to a lower energy level within an atom. This type of radiation has specific energies that are characteristic of the elements involved. On the other hand, bremsstrahlung radiation is produced when a high-speed electron is slowed down or deflected by the electric field of an atomic nucleus. This results in the emission of X-rays with a continuous spectrum of energies. In terms of effects, characteristic radiation is used in X-ray spectroscopy to identify elements present in a sample, while bremsstrahlung radiation is commonly used in medical imaging for diagnostic purposes due to its ability to penetrate tissues.
