What information is conveyed by the m in 99mTc?
The "m" in 99mTc indicates that the technetium is in a metastable state. This means that the technetium is in an excited nuclear state that will decay to a more stable state by emitting gamma radiation. Metastable technetium is commonly used in nuclear medicine imaging.
What is dynamic metastable equilibrium?
Dynamic Metastable Equilibrium as it relates to Geomorphology describes a system threshold that changes dramatically through time, in an otherwise steady system. In other words, it is a combination of dynamic equilibrium and metastable equlibrium. An example would be changing sea level as it respositions shorelines these changes typically ocurr over thousands of years.
In which state does the electron possess more energy?
An electron possesses more energy in the excited state than the ground state.
In matters lowest energy state does it tend to be more stable?
Yes, in general, the lowest energy state of a system tends to be more stable because it represents a state where the system has achieved a balanced and minimally energetic configuration. Systems naturally tend to move towards their lowest energy state to increase stability and minimize energy.
Is bromine more stable as gas or liquid?
Bromine is more stable in its liquid state at room temperature and pressure. In its gaseous state, bromine is highly reactive and can readily undergo reactions.

Why triplet state is found to be more stable than excited state?
Why triplet excited state is found to be more stable than singlet excited 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".
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.
What characterized a radioactive atom?
Its nucleus is unstable.
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.

What is meta stable stage?
A metastable stage refers to a state of a system that is stable under small perturbations but not under larger disturbances, meaning it can exist in a temporary equilibrium before transitioning to a more stable state. This concept is commonly encountered in physics, chemistry, and materials science, where certain phases or configurations can persist despite being energetically unfavorable. For example, in nucleation processes, a supersaturated solution can exist in a metastable state before crystals form.
What is the electron configuration of copper at excited state?
The electron configuration of copper at an excited state is [Ar] 3d104s1. In the excited state, one of the 4s electrons is promoted to the 3d orbital to achieve a half-filled d orbital, which is a more stable configuration.
In which state does the electron possess more energy?
An electron possesses more energy in the excited state than the ground state.
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
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.
