The element phosphorous (P) has an atomic number of 15 and an atomic mass of 31. How many neutrons are in an atom of phosphorous (P)?(1 point)

Answer 1

To find the number of neutrons in an atom of phosphorus (P), you can use the following formula:

Number of neutrons = Atomic mass - Atomic number

Given:

• Atomic mass of phosphorus = 31
• Atomic number of phosphorus = 15

Now, substituting the values:

Number of neutrons = 31 - 15 = 16

Therefore, an atom of phosphorus has 16 neutrons.
