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

Europium has 63 protons, 89 neutrons and 63 electrons.

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

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

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

Let’s dive right into it!

## Finding the Protons, Neutrons and Electrons in Europium

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 europium.

### #1 Number of Protons in Europium

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 Europium (Eu).

So from the above periodic table, you can see that the atomic number of europium is 63.

As the atomic number of europium is 63, it has a total of 63 protons in its nucleus.

Thus, the number of protons in Europium is 63.

### #2 Number of Neutrons in Europium

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

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

The atomic mass of europium is 151.96 u (which you can round it to 152). [2]

So from this atomic mass (i.e 152), you have to subtract its atomic number (i.e 63).

So you will get 152 – 63 = 89.

Thus, the number of neutrons in Europium is 89.

### #3 Number of Electrons in Europium

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

Here, the europium atom is a neutral atom.

So the number of electrons in europium 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 europium is 63.

Thus, the number of electrons in Europium is 63.

## Summary

Number of Protons in Europium

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Europium = Atomic number of Europium = 63

Number of Neutrons in Europium

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Europium = Atomic mass of Europium – Atomic number of Europium = 152 – 63 = 89

Number of Electrons in Europium

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Europium = Atomic number of Europium = 63

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