# Manganese Protons Neutrons Electrons (And How to Find them?)

Manganese has 25 protons, 30 neutrons and 25 electrons.

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

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

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

Let’s dive right into it!

## Finding the Protons, Neutrons and Electrons in Manganese

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 manganese.

### #1 Number of Protons in Manganese

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 Manganese (Mn).

So from the above periodic table, you can see that the atomic number of manganese is 25.

As the atomic number of manganese is 25, it has a total of 25 protons in its nucleus.

Thus, the number of protons in Manganese is 25.

### #2 Number of Neutrons in Manganese

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

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

The atomic mass of manganese is 54.938 u (which you can round it to 55). [2]

So from this atomic mass (i.e 55), you have to subtract its atomic number (i.e 25).

So you will get 55 – 25 = 30.

Thus, the number of neutrons in Manganese is 30.

### #3 Number of Electrons in Manganese

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

Here, the manganese atom is a neutral atom.

So the number of electrons in manganese 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 manganese is 25.

Thus, the number of electrons in Manganese is 25.

## Summary

Number of Protons in Manganese

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Manganese = Atomic number of Manganese = 25

Number of Neutrons in Manganese

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Manganese = Atomic mass of Manganese – Atomic number of Manganese = 55 – 25 = 30

Number of Electrons in Manganese

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Manganese = Atomic number of Manganese = 25

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