The correct arrow notation for chlorine is (c), the element with the provided electron configuration is Antimony (Sb), the element with 54 protons is Xenon (Xe), and the maximum electrons in a suborbital depend on the orbital according to the Pauli Exclusion Principle.
17. Correct Arrow Notation for Chlorine (Cl):
The correct arrow notation for chlorine (Cl) is represented by option (c):
(↓↑) (↓↑) (↓↑) (↓↑) (↓↑) (↓↑) (↓↑) (↓) (↓)
(↓↑) (↓↑) (↓↑) (↓↑) (↓↑) (↓↑) (↓↑) (↓) (↓)
This notation adheres to the Pauli Exclusion Principle, ensuring that each orbital is occupied by a maximum of two electrons with opposite spins.
18. Element with Electron Configuration: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p³:
The correct answer is (b) Antimony (Sb). Antimony has the electron configuration described in the question.
19. Element with 54 Protons:
The element with 54 protons is Xenon (Xe), represented by option (d).
20. Maximum Electrons in a Suborbital According to Pauli Exclusion Principle:
According to the Pauli Exclusion Principle, a suborbital can hold a maximum of 2 electrons. This principle dictates that electrons within an atom must have opposite spins. Therefore, the correct answer is (a) "Depends on the orbital."
