Question

how many neutrons are in a cobalt (co) atom? atomic mass: 58.933 atomic number: 27 51 32 107

Explanation:

Step1: Recall neutron - proton relationship

The number of neutrons $n$ in an atom is given by the formula $n = A - Z$, where $A$ is the atomic mass and $Z$ is the atomic number.

Step2: Identify values of A and Z

For cobalt, $A = 58.933\approx59$ (we take the whole - number approximation for mass - number calculations in this context) and $Z = 27$.

Step3: Calculate number of neutrons

$n=A - Z=59 - 27=32$

Answer:

32
