Question

A neutral atom of Cobalt (Co) has an atomic number of 27 and an atomic mass of 59. Therefore, Co has _________________________ neutrons

Answer 1

32 neutrons

Step-by-step explanation:

Step 1: Given data

Atomic number of Cobalt (Z): 27

Atomic mass of Cobalt (A): 59

Step 2: Calculate the number of neutrons

The atomic number is the number of protons, while the atomic mass is the sum of protons and neutrons. Then, we can calculate the number of neutrons using the following expression.

n⁰ = A - Z

n⁰ = 59 - 27

n⁰ = 32
