Answer:
20
27
Explanation:
Given parameters:
Atomic mass = 47
Atomic number = 20
Unknown:
Number of protons = ?
Number of neutrons = ?
Solution:
To solve this problem,
Atomic mass = number of protons + number of neutrons
Atomic number = number of protons
So;
Number of protons = 20
Now;
Number of neutrons = Atomic mass - number of protons
Number of neutrons = 47 - 20 = 27
