Question

Which of the following orbitals cannot exist? a) 2p b) 3d c) 4d d) 3f e) 162p

Answer 1

The 3f and 162p orbitals cannot exist due to violation of the electron configuration rules.

Step-by-step explanation:

The orbital configurations are determined by a set of rules called the Aufbau principle, which states that electrons fill lower energy levels before filling higher energy levels.

Based on this principle, the following orbitals cannot exist:

• d) 3f: The f subshell can only hold a maximum of 14 electrons. Since the electron configuration 3f already exceeds this limit, it is not allowed.
• e) 162p: The number 162 implies that there are 162 electrons in the 2p subshell, which violates the maximum limit of 6 electrons for the p subshell.

Answer 2

Of the given options, 3g¹¹ cannot exist as an orbital. The subshell 'g' violates the rules of electron configuration.

Step-by-step explanation:

Of the given options, 3g¹¹ cannot exist as an orbital. The subshell 'g' does not exist in the electron configuration because it violates the rules of electron configuration. The letters s, p, d, and f are the only valid subshells. The subshell 'g' violates the convention of using letters from the beginning of the alphabet to represent subshells.
