Answer:
(a) Bound electons (b) vslence elrctrons
Explanation:
- A bound electron is one that is still considered part of the atoms and its attracted to the nucleus whereas a free electron is one that absorded enough energy from protons to completely leave the atom
- valence electrons are the electrons in the outer most shell, or energy level, of a atoms. for eg. oxygen has six valence electrons, two in the 2s subsell snd four in the 2p subshell
