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

Chromium has 24 protons, 28 neutrons and 24 electrons.

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

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

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

Let’s dive right into it!

Finding the Protons, Neutrons and Electrons in Chromium

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 chromium.

#1 Number of Protons in Chromium

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 Chromium (Cr).

So from the above periodic table, you can see that the atomic number of chromium is 24.

As the atomic number of chromium is 24, it has a total of 24 protons in its nucleus.

Thus, the number of protons in Chromium is 24.

#2 Number of Neutrons in Chromium

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

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

The atomic mass of chromium is 51.996 u (which you can round it to 52). ^[2]

So from this atomic mass (i.e 52), you have to subtract its atomic number (i.e 24).

So you will get 52 – 24 = 28.

Thus, the number of neutrons in Chromium is 28.

#3 Number of Electrons in Chromium

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

Here, the chromium atom is a neutral atom.

So the number of electrons in chromium 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 chromium is 24.

Thus, the number of electrons in Chromium is 24.

Summary

Number of Protons in Chromium

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Chromium = Atomic number of Chromium = 24

Number of Neutrons in Chromium

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Chromium = Atomic mass of Chromium – Atomic number of Chromium = 52 – 24 = 28

Number of Electrons in Chromium

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Chromium = Atomic number of Chromium = 24

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