Data:
z = p = e
Using:
Zirconium [tex]Zr^{90} [/tex]
Atomic Mass (A) = 90
Atomic number (z) = 40
Neutron number (n) = ?
A = z + n
90 = 40 + n
n = 90 - 40
n = 50
Soon (Zirconium)
z = p = e
40 = 40 = 40
Protons (p) = 40
neutrons (n) = 50
Electrons (e) = 40

Using:
Antimony [tex]Sb^{123} [/tex]
Atomic Mass (A) = 123
Atomic number (z) = 51
Neutron number (n) = ?
A = z + n
123 = 51 + n
n = 123 - 51
n = 72
Soon (Antimony)
z = p = e
51 = 51 = 51
Protons (p) = 51
neutrons (n) = 72
Electrons (e) = 51
