a.In free space



b.In a box of rigid walls

Answer 1

$<b><u>$ According to me, it's answer is in free space.....


#Hope it's correct

Answer 2

a. In free space

• Only energy levels can be taken on by a quantum mechanical system or particles that is spatially bound.
• Additionally, an energy is a discrete energy value.
• This differs from classical particles, which can have any quantity of energy.
• Because of the quantum-mechanical basis of electron mobility, molecules or ions have discrete energy levels.
• The varied energies by different atomic routes are referred to as an atom's discrete energy levels.
