Cadmium Protons Neutrons Electrons (And How to Find them?)

Cadmium has 48 protons, 64 neutrons and 48 electrons.

But how will you find the number of protons, neutrons and electrons in Cadmium (Cd)?

Well, it is very easy to find the protons, neutrons and electrons of cadmium atom.

Here I have given a very simple method for finding the protons, neutrons and electrons of cadmium atom.

Let’s dive right into it!

Finding the Protons, Neutrons and Electrons in Cadmium

How to find protons?

• The number of protons can be found by knowing the atomic number of that atom. ^[1]

How to find neutrons?

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.

How to find electrons?

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.

Let’s calculate the number of protons, neutrons and electrons in cadmium.

#1 Number of Protons in Cadmium

If you have a periodic table with you, then most of the answers are in front of you.

You can see the elements, their atomic number and their atomic mass from the periodic table.

Now here our element is Cadmium (Cd).

So from the above periodic table, you can see that the atomic number of cadmium is 48.

As the atomic number of cadmium is 48, it has a total of 48 protons in its nucleus.

Thus, the number of protons in Cadmium is 48.

#2 Number of Neutrons in Cadmium

In order to find the number of neutrons of cadmium atom, you should know its atomic mass first.

The number of neutrons in cadmium can be obtained by subtracting the atomic number from its atomic mass.

The atomic mass of cadmium is 112.41 u (which you can round it to 112). ^[2]

So from this atomic mass (i.e 112), you have to subtract its atomic number (i.e 48).

So you will get 112 – 48 = 64.

Thus, the number of neutrons in Cadmium is 64.

#3 Number of Electrons in Cadmium

For a neutral atom, the number of electrons and the number of protons are the same.

Here, the cadmium atom is a neutral atom.

So the number of electrons in cadmium is equal to its number of protons (which is also equal to its atomic number).

In the beginning, we have found that the number of protons in cadmium is 48.

Thus, the number of electrons in Cadmium is 48.

Summary

Number of Protons in Cadmium

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Cadmium = Atomic number of Cadmium = 48

Number of Neutrons in Cadmium

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Cadmium = Atomic mass of Cadmium – Atomic number of Cadmium = 112 – 48 = 64

Number of Electrons in Cadmium

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Cadmium = Atomic number of Cadmium = 48

I hope you have understood the simple method for finding the protons, neutrons and electrons of cadmium atom.
