Question

Quizplus · Accepted Answer

¹³C represents the chemical formula of a molecule, which consists of different atoms. Breaking down the formula shows: - S1: 1 sulfur atom - U1: 1 unknown element (not enough information to determine its atomic number) - P113: 113 phosphorus atoms - S1: 1 sulfur atom - S1: 1 sulfur atom - P0: 0 phosphorus atoms (does not contribute to the overall count) - C: 1 carbon atom To determine the number of particles (protons, neutrons, and electrons) in the atom, we need to know the atomic number of each element. - Sulfur (S) has an atomic number of 16, meaning it has 16 protons and 16 electrons. The sulfur atoms contribute a total of 2 x 16 = 32 particles. - Carbon (C) has an atomic number of 6, meaning it has 6 protons and 6 electrons. The carbon atom contributes 6 particles. - Phosphorus (P) has an atomic number of 15, meaning it has 15 protons and 15 electrons. The 113 phosphorus atoms contribute a total of 113 x 30 = 3,390 particles. We cannot determine the atomic number (and thus the number of particles) of the unknown element (U). Therefore, the total number of particles in the atom is: 32 + 6 + 3,390 = 3,428. The only answer choice that matches this count is B.
