Spectral lines are bright or dark lines in an otherwise continuous or uniform spectrum. They are caused by an excess (emission lines) or deficiency (absorption lines) of observed photons within certain frequency ranges.
Absorption lines usually come from a background continuum; photons are absorbed when passing through matter to the observer. Absorption occurs when an electron within an atom absorbs a photons energy and is bumped up to an excited state.
Emission lines usually come from hot gases; photons are emitted from these gases and reach the observer. Emission occurs when an electron within an atom falls back down to it's ground state and releases energy in the form of a photon.
What else can I help you with?
The bohr model was inadequate because?
The Bohr model was inadequate because it couldn't fully explain the behavior of complex atoms or molecules. It couldn't account for the fine structure of spectral lines or the observed distribution of electrons in atoms. Additionally, it couldn't explain the quantum mechanical behavior of particles at the atomic level.
What is beryllium spectral lines?
Beryllium spectral lines are specific wavelengths of light emitted or absorbed by beryllium atoms when they undergo transitions between energy levels. These spectral lines are unique to beryllium and can be used in spectroscopic analysis to identify the presence of beryllium in a sample.
Use the atomic theory to explain atoms?
The atomic theory states that all matter is made up of tiny indivisible particles called atoms. Atoms are composed of a nucleus containing protons and neutrons, surrounded by electrons in orbitals. Different elements have different types of atoms, and chemical reactions involve the rearrangement of these atoms.
Do cells contain atoms explain how?
All matter is made of atoms.
What do spectral lines tell us about the internal structure of the atom?
Spectral lines tell us how many different energy levels an atom has, and how far apart those energy levels are spaced. This is possible because spectral lines are the result of an excess (emission lines) or deficiency (absorption lines) of observed photons emitted from certain types of matter. The lines are caused by electrons moving between energy levels within individual atoms. Since each element emits it's own unique spectrum, this means that different types of atoms must have a distinct number of electrons in very particular energy levels.
What is the significance of degeneracy in the hydrogen atom?
In the context of the hydrogen atom, degeneracy refers to the phenomenon where different electron states have the same energy level. This is significant because it helps explain the spectral lines observed in the hydrogen spectrum, providing insights into the behavior of electrons in atoms.
How do Spectra from neutral atoms compared with spectra from ionized atoms of the same element?
Spectra from neutral atoms show a series of discrete lines corresponding to transitions between different energy levels within the atom. These lines are unique to each element and can be used to identify the element. When an atom is ionized, electrons are removed, leading to changes in the energy levels and resulting in a different set of spectral lines. The spectra from ionized atoms will have different line patterns and energy levels compared to those of neutral atoms of the same element.
How can we understand the behavior of atoms by considering thermometers as speedometers for atoms?
By using thermometers as speedometers for atoms, we can measure the kinetic energy of atoms, which is related to their speed. This helps us understand how atoms move and behave in different conditions, providing insights into their behavior and interactions.

What scientist suggested that electrons have fixed orbits?
Niels Bohr proposed the idea that electrons have fixed orbits around the nucleus of an atom in his model of the atom in 1913. This concept helped to explain the stability of atoms and the spectral lines observed in hydrogen.
Do Atoms affect Earth?
You might say that, considering that the Earth and everything on it are composed of atoms.

Why atoms in molecule produce spectrum different to spectrum produced when they are separate?
Here is the simplified version, the full explanation requires some knowledge of quantum physics. The spectrum a particle produces during emission spectroscopy is dependant on the arrangement of the electrons associated with the particle. Spectral lines are produced dependant on the energy levels that quantum physics allows the electrons to exist in. When a molecule is formed, the electrons from the component atoms are moved into a different arrangement to facilitate the formation of a chemical bond. This rearrangement changes the energy levels and thus changes the spectral lines produced. In addition, a molecule is capable of rotation, this rotation produces additional spectral lines.
