My Isotopes
What is isotopes????
Ramai pelajar yang selalu memberikan jawapan yang tidak tepat tentang isotope. contohnya seperti berikut :
i) Isotope have same proton number but different nucleon number
( mempunyai nombor proton yang sama tetapi nombor nukleon yang berbeza )
ii) Isotope have same proton number but different number of neutron
( mempunyai nombor proton yang sama tetapi nombor neutron yang berbeza )
Kenapa jawapan di atas tidak tepat ???? Macam dah betul tapi kenapa tak dapat markah.....
Kata kunci paling penting adalah ATOM...Kerana satu perkataan markah hilang. Tersangatlah rugi.
So be careful. Inilah jawapan yang tepat...

JIRIM (Matter)
JIRIM BOLEH BERUBAH (MATTER)
Mood kita juga sering berubah mengikut keadaan kita pada satu-satu masa.Mengapa ia terjadi? Apa kaitan mood dan jirim?
Berdasarkan Teori Kinetik Jirim, jirim ini sebenarnya boleh berubah-ubah. Jirim adalah bahan yang mempunyai jisim dan memenuhi ruang.Ianya terdiri daripada zarah-zarah halus yang diskrit.Maknanya, zarah ini tidak boleh dilihat dengan mata kasar...
