How many protons, neutrons, and electrons does the atom ³¹P have?

Question

Quizplus · Accepted Answer

The symbol ³¹P can be broken down into its individual elements: S1 - one atom of sulfur U1 - one atom of uranium P131 - 131 atoms of phosphorus S1 - one atom of sulfur S1 - one atom of sulfur P0 - zero atoms of phosphorus Using the periodic table, we can determine the number of protons and electrons in each element: Sulfur (S) has 16 protons and 16 electrons Uranium (U) has 92 protons and 92 electrons Phosphorus (P) has 15 protons and 15 electrons To calculate the number of neutrons, we subtract the number of protons from the atomic mass: Sulfur-32 (S1) has (32-16) 16 neutrons Uranium-238 (U1) has (238-92) 146 neutrons Phosphorus-31 (P131) has (131-15) 116 neutrons Sulfur-32 (S1) has (32-16) 16 neutrons Sulfur-32 (S1) has (32-16) 16 neutrons Phosphorus-31 (P0) has (31-15) 16 neutrons (note that even though there are zero atoms of phosphorus, the number of neutrons is still calculated based on the atomic mass) Adding up the totals for each particle, we get: 15 protons, 16 neutrons, and 15 electrons for a total of 46 particles, which matches answer choice E.
