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

Ruthenium has 44 protons, 57 neutrons and 44 electrons.

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

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

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

Let’s dive right into it!

Finding the Protons, Neutrons and Electrons in Ruthenium

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 ruthenium.

#1 Number of Protons in Ruthenium

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 Ruthenium (Ru).

So from the above periodic table, you can see that the atomic number of ruthenium is 44.

As the atomic number of ruthenium is 44, it has a total of 44 protons in its nucleus.

Thus, the number of protons in Ruthenium is 44.

#2 Number of Neutrons in Ruthenium

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

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

The atomic mass of ruthenium is 101.07 u (which you can round it to 101). ^[2]

So from this atomic mass (i.e 101), you have to subtract its atomic number (i.e 44).

So you will get 101 – 44 = 57.

Thus, the number of neutrons in Ruthenium is 57.

#3 Number of Electrons in Ruthenium

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

Here, the ruthenium atom is a neutral atom.

So the number of electrons in ruthenium 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 ruthenium is 44.

Thus, the number of electrons in Ruthenium is 44.

Summary

Number of Protons in Ruthenium

• The number of protons can be found by knowing the atomic number of that atom.
• Number of Protons in Ruthenium = Atomic number of Ruthenium = 44

Number of Neutrons in Ruthenium

• The number of neutrons can be found by subtracting the atomic number from its atomic mass.
• Number of Neutrons in Ruthenium = Atomic mass of Ruthenium – Atomic number of Ruthenium = 101 – 44 = 57

Number of Electrons in Ruthenium

• For a neutral atom, the number of electrons can be found by knowing the atomic number of that atom.
• Number of Electrons in Ruthenium = Atomic number of Ruthenium = 44

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