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

Tungsten has 74 protons, 110 neutrons and 74 electrons.

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

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

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

Let’s dive right into it!

Finding the Protons, Neutrons and Electrons in Tungsten

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 tungsten.

#1 Number of Protons in Tungsten

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 Tungsten (W).

So from the above periodic table, you can see that the atomic number of tungsten is 74.

As the atomic number of tungsten is 74, it has a total of 74 protons in its nucleus.

Thus, the number of protons in Tungsten is 74.

#2 Number of Neutrons in Tungsten

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

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

The atomic mass of tungsten is 183.84 u (which you can round it to 184). ^[2]

So from this atomic mass (i.e 184), you have to subtract its atomic number (i.e 74).

So you will get 184 – 74 = 110.

Thus, the number of neutrons in Tungsten is 110.

#3 Number of Electrons in Tungsten

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

Here, the tungsten atom is a neutral atom.

So the number of electrons in tungsten 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 tungsten is 74.

Thus, the number of electrons in Tungsten is 74.

Summary

Number of Protons in Tungsten

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Tungsten = Atomic number of Tungsten = 74

Number of Neutrons in Tungsten

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Tungsten = Atomic mass of Tungsten – Atomic number of Tungsten = 184 – 74 = 110

Number of Electrons in Tungsten

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Tungsten = Atomic number of Tungsten = 74

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