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... the first shell shouldnt have 3 electrons. no shell can hold more than 2 electrons. the second shell cant have 4 electrons. the first shell must fill before the second shell can have electrons. the second shell should have 8 electrons. submit request answer 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:

For the first part, the first electron - shell (K - shell) can hold a maximum of 2 electrons. Dr. Jones' claim of 3 electrons in the first shell is incorrect. For the second part, electrons must gain energy to move to a higher - energy shell (from first to second), and the valence shell has higher energy than inner occupied shells.

Answer:

First part: the first shell shouldn't have 3 electrons.
Second part: The valence shell has higher energy than other occupied shells.
