Learning the atomic number of elements can be a daunting task for many students, as there are 118 elements on the periodic table. However, there is a trick that can help you quickly memorize the atomic numbers of the first 20 elements, which are the most commonly studied elements in chemistry. In this tutorial, I will show you how to use mnemonics to remember the atomic numbers of these elements with ease.
Mnemonics are memory aids that use associations to help you recall information more easily. In this case, we will use a mnemonic sentence that will help you remember the atomic numbers of the first 20 elements in order. The sentence we will use is:
Harry
He
Lies
Below
Boron
Carbon
Noble
Fart
Nostalgically
Neon
Silly
Patrolling
A
Skinny
Clown
Arguing
Pretty
Silver
Clad
In
Gold
Now, let’s break down this sentence and associate each word with the corresponding atomic number:
1. Harry – Hydrogen (Atomic Number 1)
2. He – Helium (Atomic Number 2)
3. Lies – Lithium (Atomic Number 3)
4. Below – Beryllium (Atomic Number 4)
5. Boron – Boron (Atomic Number 5)
6. Carbon – Carbon (Atomic Number 6)
7. Noble – Nitrogen (Atomic Number 7)
8. Fart – Oxygen (Atomic Number 8)
9. Nostalgically – Fluorine (Atomic Number 9)
10. Neon – Neon (Atomic Number 10)
11. Silly – Sodium (Atomic Number 11)
12. Patrolling – Magnesium (Atomic Number 12)
13. A – Aluminum (Atomic Number 13)
14. Skinny – Silicon (Atomic Number 14)
15. Clown – Phosphorus (Atomic Number 15)
16. Arguing – Sulfur (Atomic Number 16)
17. Pretty – Chlorine (Atomic Number 17)
18. Silver – Argon (Atomic Number 18)
19. Clad – Potassium (Atomic Number 19)
20. In – Calcium (Atomic Number 20)
By using this mnemonic sentence, you can easily remember the atomic numbers of the first 20 elements in order. Practice saying the sentence and associating each word with the corresponding element and atomic number. With enough repetition, you will have the atomic numbers memorized in no time.
This trick can also be applied to other elements on the periodic table, but for now, focus on mastering the first 20 elements. Once you have those down, you can explore more mnemonics and tricks to learn the atomic numbers of the remaining elements. Happy studying!
Bhaiya atoms and molecules ke imp questions bta do 😅
Sir thank you for teaching
Well done sir 👍
Nice video bhaiya
Bhaiya this video is very helpful thank you bhaiya 😊😊
