Which statement correctly describes excitation in the context of electron transitions?.
- A.Excitation results in the atom becoming ionised and losing an electron.
- B.Excitation involves an electron moving to a higher energy level without leaving the atom.
- C.Excitation can only occur in gases at high temperatures.
- D.Excitation requires the release of energy from the atom.
Model answer
What a good answer should say
- Excitation involves an electron moving to a higher energy level without leaving the atom.
Explanation
Why this works
Excitation specifically refers to the process where an electron absorbs energy and transitions to a higher energy level within the atom, remaining bound to the nucleus. This is distinct from ionisation, where the electron is completely removed from the atom.
Excitation can occur under various conditions, not just at high temperatures, and it involves energy absorption rather than release. Therefore, the correct description of excitation is that it keeps the electron within the atom while raising its energy state.
