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

Rhenium has 75 protons, 111 neutrons and 75 electrons.

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

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

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

Let’s dive right into it!

## Finding the Protons, Neutrons and Electrons in Rhenium

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 rhenium.

### #1 Number of Protons in Rhenium

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 Rhenium (Re).

So from the above periodic table, you can see that the atomic number of rhenium is 75.

As the atomic number of rhenium is 75, it has a total of 75 protons in its nucleus.

Thus, the number of protons in Rhenium is 75.

### #2 Number of Neutrons in Rhenium

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

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

The atomic mass of rhenium is 186.207 u (which you can round it to 186). [2]

So from this atomic mass (i.e 186), you have to subtract its atomic number (i.e 75).

So you will get 186 – 75 = 111.

Thus, the number of neutrons in Rhenium is 111.

### #3 Number of Electrons in Rhenium

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

Here, the rhenium atom is a neutral atom.

So the number of electrons in rhenium 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 rhenium is 75.

Thus, the number of electrons in Rhenium is 75.

## Summary

Number of Protons in Rhenium

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Rhenium = Atomic number of Rhenium = 75

Number of Neutrons in Rhenium

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Rhenium = Atomic mass of Rhenium – Atomic number of Rhenium = 186 – 75 = 111

Number of Electrons in Rhenium

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Rhenium = Atomic number of Rhenium = 75

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