The isotope notation
Solution
Isotopes are elements that have the same atomic number with a different mass number
The following element notation,
X = symbol of element
A = mass number
= number of protons + number of neutrons
Z = atomic number
= number of protons = number of electrons, on neutral elements
So the mass number of element = 53 + 20 = 73
Atomic number = 53
The symbol :
