Indicate whether the statements below are true or false. if a statement is false, explain why it is false a electrons are constantly moving around the nucleus of the atom, but they can move only in discrete regions. b. there is no limit to the number of electrons that can occupy the fourth electron shell. c. atoms with unfilled outer electron shells are especially stable and are therefore less reactiv d. covalent bonds are formed when electrons are either shared or transferred between atoms.

B. There is no limit to the number of electrons that can occupy the fourth electron shell.

C. Atoms with unfilled outer electron shells are especially stable and are therefore less reactive

Explanation:

The shell which is the outer most cannot hold more than 18 electrons. The number of electrons in the shell is given by the Aufbau principle. The rule states that when an atom is in the ground state the electrons have occupy the lowest level of energy.

If in the outer shell is unfilled then it will try to attract electrons and will be easilly reactive.

If the outer shell is filled then it has the required number of electrons and does not need to attract electrons hence it will be stable and non reactive.
