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 metastable state is more stable then excited state?
because according to energy profile,metastable state is lying lower than excited state.as we know that states of lower energies are more stable than states of higher energy.so it is more stable than excited state.
Is an excited state is less stable than a ground state?
Yes.
What has the author Dewey William Warner written?

What is energized oxygen?
Energized oxygen is known as oxygen in an excited state (high energy). ... Excited state is when any atom/molecule (oxygen in this case) is not on ground state (most stable state). all atoms want to be on ground state because it is the most stable. In order to energize/ excite oxygen, energy has to be put in (for example, by the absorption of a photon of an appropriate energy). After excitation, all atoms want to return to ground state so they release the energy by emitting a specific energy. Excited oxygen is sometimes referred to singles oxygen while ground state oxygen is referred to as triplet oxygen, this is best explained by Molecular orbital theory.
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".
Why does a compound in the excited triplet state undergo intersystem crossing before returning to the ground state?
it actually does not. intersystem crossing is what creates the triple state not what reduces it to its ground state. it happens in a series of steps... first you have the excited singlet state created by photon absorption which would generally immediately emit flouresence to return to the ground state. however, if it does not emit flouresence than it becomes subject to intersystem crossing (ISC). ISC can cause an electron to invert its rotation and begin the same orbital rotation path of another electron, therefore creating the triplet state (two electrons having same directional orbit). the triplet state then undergoes internal conversion, again altering those two electrons in question. Now, when the triplet is reduced to the ground state it emits phosphorescence instead of flourescence.
What does it mean to say that an atom is an exited state?
It's actually an "excited" state and is referencing the number of protons/electrons that a particular atom has obtained outside of its normal/stable state.
The electron configuration for a Sulfur atom in the excited state?
It depends on the atom. For example, the electron configuration of an atom of boron in the ground state is 2-3. In the excited state, it would be 2-2-1. For an atom of chlorine, the ground state configuration is 2-8-7. The excited state would be 2-8-6-1. When an atom enters the excited state, an electron moves up to a higher energy level and releases energy. An electron in the excited state is not stable until it returns to ground state.
What is a sentence for frenzy?
The ants were in an excited, frenzied state because they found food.
When a molecule absorbs a photon one of the electron is raised in what state?
This electron is in an excited unstable state.
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
