Answer:
The number of protons and neutrons of antimony is 51 and 71 respectively.
Explanation:
We have for antimony:
A: mass number = 122
Z: atomic number = 51
The atomic number is equal to the number of protons, hence the antimony has 51 protons.
The mass number is:
[tex] A = Z + N [/tex]
Where:
N: is the number of neutrons
Then, the number of neutrons is:
[tex] N = A - Z = 122 - 51 = 71 [/tex]
Therefore, the number of protons and neutrons of antimony is 51 and 71 respectively.
I hope it helps you!
