The atom absorbs energy, and one or more electrons move to a higher electron shell
What else can I help you with?
What has a higher energy ground state or excited state?
ground
Why do elements go from ground state to excited state?
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.
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.
What is HTE difference between an atom in the ground state and an atom in an excited state?
Atom in the ground state is stable but atom in excited state is not stable the main reason for this is their energies.Atoms in excited state has more energy so they undergo chemical reaction so they are not stable but atoms in ground state has less energy than the excited state so they dont undergo chemical reaction.
Why existence of metastable state is an essential requirement for achieving population inversion?
A metastable state is crucial for achieving population inversion because it allows excited atoms or molecules to remain in an excited state longer than they typically would. This extended lifetime increases the probability of stimulating emission, as more particles can accumulate in the excited state before decaying to the ground state. In contrast, if the excited state decays too quickly, it becomes challenging to achieve enough population in the excited state to exceed that in the ground state, which is necessary for laser action. Thus, the existence of a metastable state is vital for maintaining the conditions conducive to population inversion.
Is an excited state is less stable than a ground state?
Yes.
In which state does the electron possess more energy?
An electron possesses more energy in the excited state than the ground state.
What is the opposite of ground state?
Excited state is the opposite of ground state in the context of atoms and molecules. Ground state refers to the lowest energy state of an atom or molecule, while excited states have higher energy levels due to the absorption of energy.
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
When an atom in an excited state returns to it's ground state what happens to the energy?
When an atom in an excited state returns to its ground state, it releases energy in the form of electromagnetic radiation, typically as light or photons. The energy released corresponds to the difference in energy between the excited state and the ground state. This phenomenon is fundamental to processes such as fluorescence and the emission spectra of elements.
Does a hydrogen atom expand or contract as it moves from its ground state to an excited state?
A hydrogen atom expands as it moves from its ground state to an excited state. This is because the electron in the excited state is farther away from the nucleus, increasing the average distance between the electron and proton in the atom.
