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.

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 colors of visible light are found in the emission spectrum of hydrogen?
Red, blue, green, and violet are found in the emission spectrum of hydrogen.
The absorption spectrum of a hydrogen atom contains dark bands at specific wavelengths The emission spectrum of a hydrogen atom contains bright bands at the same wavelengths Explain what causes ther?
The short answer is these bands represent the (frequency) wavelengths which correspond to orbital configurations for the atom (matter). Absorption is used to identify chemical bonds of elements & compounds by radiating a substance across a range of frequencies & measuring the magnitude of the signal at these frequencies in chemical analysis of a sample. Emission is based upon the same principle except that the substance is heated to the point that it emits radiation (light).
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.
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.
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 model of hydrogen atom how is hydrogen's emission spectrum produced?
In the Bohr model of the hydrogen atom, electrons can transition between energy levels by emitting or absorbing photons. When an electron falls from a higher energy level to a lower one, it releases energy in the form of a photon, which corresponds to a specific wavelength. The emission spectrum of hydrogen is produced when electrons transition from higher to lower energy levels, resulting in the release of photons with distinct wavelengths that correspond to specific spectral lines.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.

Is the Hg emission spectrum continuous or discrete?
Hg emission is discrete, that's why you can only see certain (discrete) frequencies, as excited electrons fall from one level to another. A heated light bulb, on the other hand, emits a continuous spectrum from all of its variously vibrating charges.
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.
The lines in the bright line spectrum of an atom are due to what?
The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.
When is the characteristic bright-line spectrum of an atom produced?
In the laboratory in a flame test. Electrons are excited to higher energy levels and when they fall back light is emitted. The frequency (colour), v is related to the energy by Plancks equation, E=hv
How is the bright light spectra of elements produced?
An emission or absorption line in a spectrum that arises when an electron moves between two energy levels in an atom. A jump to a higher level requires an input of energy, and produces a dark absorption line. A drop to a lower level releases energy, producing a bright emission line.
What do we see when electrons jump?
When electrons jump to a higher energy level in an atom, they absorb energy. When they fall back down to their original energy level, they release energy in the form of light, creating an emission spectrum. This is what we see as distinct colored lines in a spectroscope.
