Explanation:

Step1: Recall atomic number of Bohrium

Bohrium has an atomic number ($Z$) of 107.

Step2: Recall mass - number formula

The mass - number ($A$) is the sum of protons and neutrons. For Bohrium - 269, $A = 269$. The number of neutrons ($N$) is given by $N=A - Z$.

Step3: Calculate number of neutrons

$N = 269-107=162$.

Answer:

162
