- Q1According to Bohr's model, which statement best describes the energy levels of electrons in an atom?Electrons are confined to the nucleus of the atom.Electrons occupy discrete energy levels or shells.Electrons can exist anywhere within the atom.Electrons are randomly distributed within the atom.30s
- Q2Which model introduced the concept of electron orbitals?Dalton's modelBohr's modelRutherford's modelQuantum mechanical model30s
- Q3Which model correctly describes the behavior of electrons in terms of both particles and waves?Bohr's modelThomson's modelRutherford's modelQuantum mechanical model30s
- Q4Which model proposed that electrons orbit the nucleus in specific energy levels?Dalton's modelRutherford's modelBohr's modelQuantum mechanical model30s
- Q5According to Bohr's model, what happens when an electron in an atom transitions from a higher energy level to a lower energy level?The electron becomes unstable and leaves the atom.The electron gains energy and moves to a higher energy level.Energy is absorbed from the surroundings.Energy is emitted in the form of light.30s
