The atom absorbs energy, and one or more electrons move to a higher electron shell
ground
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay 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".
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.
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.
Yes.
An electron possesses more energy in the excited state than the 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.
more electrons than an atom in the ground 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.
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.
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.
