Answer:

Atomic number = 15

Element = Phosphorous.

Explanation:

Hello,

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

[tex]Neutrons=Mass\ Number-Protons\\[/tex]

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

[tex]Protons=Mass\ Number-Neutrons\\\\Protons=32-17=15[/tex]

Therefore, the element is phosphorous.

Best regards.
