A nucleus with 16 protons and 16 neutrons, with electrons in orbits: 2 in the first shell, 8 in the second shell, and 8 in the third shell.
C
A nucleus with 16 protons and 16 neutrons, with electrons in orbits: 2 in the first shell, 8 in the second shell, and 6 in the third shell.

Verified step by step guidance1
Understand the Bohr model: The Bohr model describes atoms with electrons in fixed orbits around the nucleus. Each orbit corresponds to a specific energy level or shell.
Identify the atomic number of sulfur: Sulfur has an atomic number of 16, which means it has 16 protons in its nucleus.
Determine the number of electrons: Since sulfur is neutral, it also has 16 electrons to balance the 16 protons.
Distribute electrons in shells according to the Bohr model: The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 18 electrons, but for sulfur, only 6 electrons are needed to complete the third shell.
Verify the electron configuration: For sulfur, the correct electron configuration in the Bohr model is 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell, matching the correct answer provided.
