Question

the 3p subshell in the ground state of atomic iodine contains ---------- electrons. 2 5 6 6 10

Explanation:

Iodine has an atomic number of 53. Its electron configuration follows the Aufbau principle. The 3p subshell is part of the third energy level (n=3) and a p subshell can hold a maximum of 6 electrons. For elements beyond the third period, the 3p subshell is fully filled before higher energy levels are occupied. Thus, the 3p subshell in iodine contains 6 electrons.

Answer:

6 (Note: The duplicate 6 option is likely a typo; the correct choice is 6.)
