Answer:
20 neutrons
Explanation:
Since its an anion so it has gained 1 electron so no of electrons in its atom would be 18 -1 = 17.
17 = Number of electons = Number of protons
Mass number = No. of protons + No. of neutrons
37 = 17 + No. of neutrons
No. of neutrons = 37 - 17 = 20
Number of neutrons = 20
