Aku dapat contoh soalan ni dari dalam buku yg aku guna masa sekolah dulu (amboi mcm dah lama je padahal baru tahun lepas)
hehehehe

I hope that this sample question can help you all okay !



a). Why sodium atom is more reactive/electropositive than lithium atom?

Suggeted answer:
-Proton namber sodiumis bigger than lithium.
-Atomic size sodium is bigger.
-Distance between nucleus and valence electron is far.
-Attraction between nucleus and valence electron is weak.
-Tendency to release electron more easily.

b). Why fluorine atom is more reative/electropositive than chlorine atom?

Suggested answer:
-Proton number fluorine is smaller than chlorine.
-Atomic size fluorine is smaller.
-Distance between nucleus and valence electron is short.
-Attraction between nucleus and valence electron is strong.
-Tendency to release electron is increases.

c). Why atomic size of sodium is bigger/electropositive than chlorine?

Suggested answer:
-Proton number sodium is bigger than chlorine.
-Attraction between nucleus and valence electron is weak.
-Atomic size of sodium is bigger.

d). Why chlorine atom is more electropositive than magnesium atom?

Suggested answer:
-Proton number chlorine is smaller.
-Atomic size of chlorine is smaller.
-Attraction between nucleus and outer electron is strong.
-Tendency to receive electron is increases.


maafkan aku kalau ada tersilap ke apa ke,aku hanyalah manusia biasa dan tidak sempurna.
ceywah !!!
okaylah selamat belajar adik-adik semua.
