Question

An atom has a mass number of 32 and 17 neutrons. What is the atomic number of this atom?

Answer 1

The atomic number would be 15

Answer 2

Atomic number = 15

Element = Phosphorous.

Step-by-step explanation:

Hello,

In this case, taking into account that the neutrons are obtained through the following equation:

`Neutrons=Mass\ Number-Protons\\`

In such a way, the protons match with the element's atomic number and therefore its identity, thus:

`Protons=Mass\ Number-Neutrons\\\\Protons=32-17=15`

Therefore, the element is phosphorous.

Best regards.
