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

Neon has 10 protons, 10 neutrons and 10 electrons.

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

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

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

Let’s dive right into it!

Finding the Protons, Neutrons and Electrons in Neon

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 neon.

#1 Number of Protons in Neon

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 Neon (Ne).

So from the above periodic table, you can see that the atomic number of neon is 10.

As the atomic number of neon is 10, it has a total of 10 protons in its nucleus.

Thus, the number of protons in Neon is 10.

#2 Number of Neutrons in Neon

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

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

The atomic mass of neon is 20.180 u (which you can round it to 20). [2]

So from this atomic mass (i.e 20), you have to subtract its atomic number (i.e 10).

So you will get 20 – 10 = 10.

Thus, the number of neutrons in Neon is 10.

#3 Number of Electrons in Neon

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

Here, the neon atom is a neutral atom.

So the number of electrons in neon 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 neon is 10.

Thus, the number of electrons in Neon is 10.

Summary

Number of Protons in Neon

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Neon = Atomic number of Neon = 10

Number of Neutrons in Neon

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Neon = Atomic mass of Neon – Atomic number of Neon = 20 – 10 = 10

Number of Electrons in Neon

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Neon = Atomic number of Neon = 10

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