If I know the explicit form of potential, the energy and a specific eigenstate, but I don't know the general form of eigenstates and eigenvalues, can I tell if the state is ground state or not?

I think you can prove this statement by noting that the ground state wave function minimizesclem said:A ground state wave function usually has no nodes.
The ground state of an atom or molecule is the lowest energy state that it can exist in. This means that all of its electrons are in their lowest possible energy levels. To determine if a state is a ground state, you can analyze the energy levels of the electrons and compare them to the energy levels of other possible states.
Yes, the ground state of an atom or molecule can change if it gains or loses energy. This can happen through various processes such as absorption or emission of light, collisions with other particles, or changes in temperature.
The ground state is important in chemistry because it is the most stable state of an atom or molecule. This means that in most cases, atoms and molecules will naturally exist in their ground state. Additionally, the ground state forms the basis for understanding the properties and behavior of atoms and molecules.
Calculating the ground state energy requires knowledge of the electronic structure of the atom or molecule. This can be done using mathematical models such as the Schrödinger equation and quantum mechanics principles. These calculations can be complex and often require computer programs to accurately determine the ground state energy.
No, different atoms or molecules cannot have the same ground state energy. Each atom or molecule has a unique electronic structure, resulting in different energy levels for its electrons. This means that even if two atoms or molecules have similar properties, their ground state energies will be different.
