What is convergent limit in spectroscopy?
In spectroscopy, the term "convergent limit" refers to the minimum energy level that an electron in an atom can occupy. When an electron moves from a higher energy level to a lower one, it emits a photon of energy that corresponds to the difference in energy between the two levels. As the electron moves closer to the nucleus, the energy levels become closer together, and the energy required to move the electron becomes larger. At some point, the energy required to move the electron becomes so large that it is equal to the energy of a photon in the ultraviolet or X-ray range. At this point, the electron can no longer move to a lower energy level by emitting a photon, and the energy levels are said to have reached their "convergent limit." This limit is different for each atom and is determined by the size and charge of the nucleus. The convergent limit is an important concept in spectroscopy because it determines the highest energy photon that can be emitted by an atom. By analyzing the wavelengths of the emitted photons, scientists can determine the energy levels of the electrons in the atom and gain insights into its structure and properties. Overall, the convergent limit is a fundamental concept in spectroscopy that helps scientists understand the behavior of electrons in atoms and the interactions between light and matter.
Why are electron in the electron cloud?
electron cloud refers to orbit present in the atom and electron can can be revolved by the orbit only as it is an imaginary path made of energy
What is energy released on adding an electron to an isolated gas phase atom?
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.
What term refers to the average kinetic energy of the particles of a substance?
Temperature refers to the average kinetic energy of a suubstance. The higher the average kinetic energy, the higher the temperature.
Energy levels in an atom?
Energy level in an atom refers to the energy due to atoms bound in an electric field. When an electron jumps from higher energy to lower energy it releases a photon, which has a wavelength.
Difference between energy level and energy band?
An energy level refers to a confined particle such as an atom, the energy level refers to how excited the electron is ie if an electron in the ground state (level 0) receives the correct amount of energy it will move to level 1.Energy band refers to something much more complex, it is more commonly known as band structure and describes all the energy levels that a particle such as an electron is allowed to be in and those which it is not.Basically, energy level is for a single confined particle, energy band is for when lots and lots of electrons come together for instance in a crystal structure
If one molecule has more energy than another does it have a higher activation energy?
The activation energy refers to a chemical reaction.
Is excited state of electron have valence electrons?
Normally, yes. 'Ground state' refers to electrons that are unexcited (meaning not pushed to a higher energy level) by heat or electricity. So basically, yes, valence electrons are always at ground state. I mean, unless you're sending an electrical current through the substance.
Does a higher value of n mean a higher or lower energy?
The pricipal energy levels (of an atom) increase as -1/n2 (they get less negative).
Why do atoms emit only certain wavelengths of light?
The electrons in an atom's "electron shell" all have specific energy levels. If you add energy to an atom, the atom will absorb a specific amount of energy, and the electron will jump up to a higher energy level. Each different element has its own energy levels, and it can only absorb energy in specific amounts. (When you add a lot of energy to the atom, the atom becomes ionized, as one or more electrons absorb enough energy to break free of the atom completely, leaving the atom with an unbalanced positive electrical charge.) When those "excited" or jumped-up electrons release the energy, the electron drops back to its previous level, and the atom (or more specifically, the electron) emits a photon, which is a particle of light. Each photon has a frequency or energy that is distinctive to the element and the energy level. Electrons cannot have intermediate energies; they absorb and release exact "packets" or "quanta" of energy. This is how a mass spectrometer works; the operator ionizes a sample of the material that he wants to analyze, and watches the resulting spectrum. Each wavelength of light emitted by the sample corresponds to one specific element.
What does gravitional energy mean?
It refers to potential energy (energy of position), related to the force of gravity. Basically, at a higher position, an object has more energy than at a lower position.
