Just sharing ways for me to hafal kumpulan 1, 2, 17 n 18 dalam Periodic Table of Elements!

Kumpulan 1

“waH, LuNaK betul suaRa Cik Farah”

H, Li, Na, K, Rb, Cs, Fr
Hydrogen, Lithium, Sodium, Potassium, Rubidium, Caesium, Francium

Kumpulan 2

“Beli Mangga, Cari Sayur, Baru Rasa”

Be, Mg, Ca, Sr, Ba, Ra
Beryllium, Magnesium, Calcium, Strontium, Barium, Radium

Kumpulan 17

“Fattah Cuba Beri Isi Ayam Tepung”

F, Cl, Br, I, At, Ts
Fluorine, Chlorine, Bromine, Iodine, Astatine, Tennessine

Kumpulan 18

“Helang Nenek Ambik Kari Xeron nak Rasa Odang”

He, Ne, Ar, Kr, Xe, Rn, Og
Helium, Neon, Argon, Krypton, Xeron, Radon, Oganesson


Harap membantu!!

Kala 3

“Nak Makwe Alim, bakal Suami Perlu Sentiasa Cukup Agama”

Na, Mg, Al, Si, P, S, Cl, Ar
Sodium, Magnesium, Aluminium, Silicon, Phosphorus, Sulphur, Chlorine, Argon

📍Na, Mg -> Alkaline
📍Al -> Amphoteric
📍Si, P, S, Cl, Ar -> Acidic

Semakin ke kanan;
1. Electronegativity increases (tendency to accept electrons)
2. Number of protons increase (charge in the atom’s nucleus increase)
3. Atomic size decrease (Atomic radius decrease (sbb charge dkt atom’s nucleus kuat, jadi dia tarik shell electron mendekati atom’s nucleus)
4. Metal -> semi-metal -> non-metal

cepat studyy, jangan procrastinate

saya memerlukan pertolongan

hihi makasihhhh 🤍🤍
