Question

dr. jones says an atom has 3 electrons in the first shell and four electrons in the second shell. someone should tell dr. jones that... part d which statement is true of the energy levels of electrons in shells? electrons must lose energy to move from the first to the second shell. the valence shell has higher energy than other occupied shells. all the electrons in an atom have similar amounts of energy. all of the above. none of the above.

Explanation:

Electrons need energy to move to higher - energy shells. The first shell can hold a maximum of 2 electrons, and the second shell can hold a maximum of 8 electrons. Electrons in different shells have different energy levels. The valence shell (outermost shell) has higher energy than inner - occupied shells.

Answer:

All of the above.
