Esok start sklh, semua dh bersedia ke? It's going to be a new day, make the most of it, okay?

hi korangggg 🙈 , min tengok banyak yang salah soalan 10 😩 , 38% je betul , susah ke gesss ?? takpe ii , meh sini min bagi explanation , harap membantu korang (btw ni berkaitan bab 2 F5)

Let us start with form 4 chapter 2 first


This is the concept map in your textbook... I think this is the good beginning of form 4 students this year because it's a quite easy and popular topic in exam
For form 5,don't forget to revise this topic...

I will start some quiz about Chapter 2 later ya..2.1 first

The last question does not contain BM version due to some technical issues.
If you manage to answer correct all questions,that's mean you already master in 2.1 and the questions is from SPM trial paper 2024...If you wrong any question,make sure to ask and understand why you wrong
You all can leave a comment in discussion and I will answer you.

Good night

Hiiiii everyone, I hope it's nottt tooo lateee to sayyy hii to all of youu. I'm Harshinii , new adminnn for this channel but you can call me Hazell. I know some of you may have a little hope for chemistry but let me tell youu something, for my first chemistry test I got 48 ( E ) , and I don't know why, that made me to hate chemistry but then I realized if you want to score , you must love a subject first, make it as your friend so I tried my best to make chemistry as my friend and I did it , I scored 65 ( B+) afterwards , I'm not ashamed of sharing my marks because I want to tell all of you that no matter where you are all now, you still have the chance and power to start a new beginning for yourself. Btw I am a form 5 student this year and I really want to score chemistry with all my fellow mates here. Nice to meet all of you and I believe you guys can scoree At in Chemistry. ✨🕊️💫

Basic chapter to score to at least get A- in Chemistry

1. Chapter 2 F4 Chemistry
2. Chapter 3 F4 Chemistry
3. Chapter 4 F4 Chemistry
4. Chapter 5 F4 Chemistry

You all should know that this 4 chapters are very important because this chapters are so famous in Chemistry paper 1 and 2.

Let me know in the comment section which chapter are you guys weak so that I can test you with some questions hehe? ☺️

Do you guyss want me to give a shortcut to know which is ionic compound and covalent compound? If yess plss comment beloww hihi 🫣☺️

Okayy , so it's like this for Sodium Chloride , you can see that Sodium is in group one and Chloride is in group 17 so Group one , we know it's a positively charged ion group and group 17 is a negatively charged ion group so it's a hundred percent ionic compound yahoo.
For Cl2 is a covalent compound why? Because Chlorine is in group 17 which is negatively ion group so it's hundred percent covalent compound.
In a simple way to say, we can identify if it's a covalent compound or ionic compound based on their charge. If the compound consist of elements with positive charge ion and negative charge ion then it's ionic compound but if both elements are negatively charged ion than it's covalent compound!

Extra info ❗️
G1 - G13 = is all positively charged ion
G14-G17 = is all negatively charged ion
BUT BE CAREFUL SOME OF THE TRANSITION ELEMENTS ARE NEGATIVELY CHARGED ION❗️ like MN and Cr but that will be taught in F5 😊

Comment beloww if the explanation helps !

I'll ask charge ion questions now, don't see notes ya 🙂‍↕️

Okayy , jadi macam ni untuk Sodium Klorida , korang boleh nampak Natrium dalam kumpulan satu dan Klorida dalam kumpulan 17 , jadi Kumpulan satu kita tahu ia adalah kumpulan ion bercas positif dan kumpulan 17 ialah kumpulan ion bercas negatif jadi ia adalah sebatian ionik. Untuk Cl2 ialah sebatian kovalen, mengapa? Kerana Klorin berada dalam kumpulan 17 iaitu kumpulan ion negatif jadi ia adalah sebatian kovalen. Secara ringkasnya, kita boleh mengenal pasti sama ada ia sebatian kovalen atau sebatian ionik berdasarkan casnya.
Jika sebatian itu terdiri daripada unsur-unsur dengan ion cas positif dan ion cas negatif maka ia adalah sebatian ionik tetapi jika kedua-dua unsur adalah ion bercas negatif maka ia adalah sebatian kovalen!

Maklumat tambahan ❗️
G1 - G13 = semuanya ion bercas positif
G14-G18 = adalah semua ion bercas negatif
TETAPI BERHATI-HATI BEBERAPA ELEMEN UNSUR PERALIHAN ADALAH ION BERCAS NEGATIF❗️ seperti MN dan Cr tetapi itu akan diajar dalam F5 BAB 1😊
Komen di bawah jika penjelasan membantu!

This is for those who don't understand in English :) I hope it helps
