Electrons were discovered by J.J. Thomson in 1897 through his experiments with cathode rays. He identified the electron as a subatomic particle, but the concept of electrons existing in specific energy states, such as ground or excited states, was developed later through quantum mechanics in the early 20th century, particularly by scientists like Niels Bohr. Bohr's model of the atom introduced the idea of quantized energy levels for electrons.
What else can I help you with?
Do atoms in the excited state have more electrons than in the ground state?
Yes, because an atom in an excited state will normally give off energy and go to a less-excited state or to its ground state. Some atoms have long-lived excited states and are called "metastable".
Will the total number of electrons change when a specific element's electrons gain energy to shift from the ground state to the excited state?
No. The atom in this case i not ionised.
Is 2-8-7 an excited state?
No, 2-8-7 does not indicate an excited state. It typically represents the electron configuration of an element in its ground state, specifically for nitrogen. An excited state would involve the electrons being in higher energy levels than the ground state configuration.
Which energy position do electrons generally want to be in the excited state the ground state the highest possible energy level the medium energy level?
Electrons generally prefer to be in the ground state, which is the lowest energy level available to them. This state is the most stable configuration, as it minimizes the energy of the atom or molecule. While electrons can be excited to higher energy states, they tend to return to the ground state, releasing energy in the process.
What is the difference between the ground state of an atom and excited state of an atom?
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
Do atoms in the excited state have more electrons than in the ground state?
Yes, because an atom in an excited state will normally give off energy and go to a less-excited state or to its ground state. Some atoms have long-lived excited states and are called "metastable".
Is the electron configuration of sodium an excited state or ground state?
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
A state in which an atom has more energy than it does at its ground state?
An atom is in an excited state when it has absorbed energy, causing its electrons to move to higher energy levels. These excited electrons are unstable and eventually return to their ground state by emitting energy in the form of light or heat.
An atom in an excited state contains more of what type of energy than the same atom in the ground state?
more electrons than an atom in the ground state
In which state does the electron possess more energy?
An electron possesses more energy in the excited state than the ground state.
An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
Ground state vs excited state?
A ground state is an outer orbital electron of an element that is at its lowest possible energy level. The electron in an excited state has a higher energy level than a ground state electron. The average distance from the nucleus is greater in the excited state than in the ground state.
What is difference between a ground state electrons configuration and an excited state configuration?
In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).
Will the total number of electrons change when a specific element's electrons gain energy to shift from the ground state to the excited state?
No. The atom in this case i not ionised.
State in which electrons have jumped to a higher energy level?
state in which electrons have absorbed energy and "jumped" to a higher energy level
Is 2-8-7 an excited state?
No, 2-8-7 does not indicate an excited state. It typically represents the electron configuration of an element in its ground state, specifically for nitrogen. An excited state would involve the electrons being in higher energy levels than the ground state configuration.
What is the difference between the ground state of an atom and excited state of an atom?
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
