STRUKTUR ATOM

MATTER / JIRIM
• PARTICLE THEORY OF MATTER / TEORI ZARAH JIRIM
– To state the particle theory of matter
Menyatakan teori zarah jirim
– To differentiate and draw the three types of particles i.e. atom, ion and molecule
Membezakan dan melukis tiga jenis zarah jirim iaitu atom, ion dan molekul
– To describe the laboratory activity to investigate the diffusion of particles in gas, a liquid and a solid. (To prove that matter is
made up of tiny and discrete particles)
Menghuraikan aktiviti makmal untuk mengkaji resapan zarah dalam gas, cecair dan pepejal (Untuk membuktikan bahawa jirim terdiri daripada
zarah-zarah yang halus dan diskrit)

• KINETIC THEORY OF MATTER / TEORI KINETIK JIRIM
– To state the kinetic theory of matter
Menyatakan teori kinetik jirim
– To relate the change of physical states of matters with energy change
Menghubungkaitkan perubahan keadaan jirim dengan perubahan tenaga
– To relate the change of energy in the particles with kinetic particle theory of matter
Menghubungkaitkan perubahan tenaga dalam zarah dengan perubahan tenaga kinetik zarah

THE STRUCTURE OF ATOMS / STRUKTUR ATOM
• HISTORY OF ATOMIC MODELS DEVELOPMENT / SEJARAH PERKEMBANGAN MODEL ATOM
– To state the contribution of scientists in the atomic structure model such as the scientists who discovered electron, proton,
nucleus, neutron and shell
Menyatakan sumbangan ahli sains kepada perkembangan model struktur atom dan ahli sains yang menemui elektron, proton, nukleus, neutron dan
petala

• SUBATOMIC PARTICLES / ZARAH-ZARAH SUBATOM
– To compare and differentiate subatomic particles i.e. proton, neutron and electron from the aspect of charge, relative mass
and location
Membanding dan membezakan zarah-zarah subatom iaitu proton, neutron dan elektron dari segi cas, jisim relatif dan kedudukan
– To state the meaning of proton number and nucleon number based on the subatomic particle
Menyatakan maksud nombor proton dan nombor nukleon berdasarkan zarah subatom
– To write the symbol of elements with proton number and nucleon number
Menulis simbol unsur yang mengandungi nombor proton dan nombor nukleon

• ISOTOPE / ISOTOP
– To state the meaning, examples and the use of isotopes
Menyatakan maksud isotop, contoh-contoh isotop dan kegunaan isotop
• ELECTRON ARRANGEMENT / SUSUNAN ELEKTRON
– To know the number of electron shells and number of electrons in the 1st, 2nd and 3rd shell
Mengetahui bilangan petala elektron serta bilangan elektron yang diisi dalam petala 1, 2 dan 3
– To write the electron arrangement of atoms based on proton number or number of electrons and state the number of valence
electron
Menulis susunan elektron bagi suatu atom berdasarkan nombor proton atau bilangan elektron dan seterusnya menyatakan bilangan elektron valens
