Pe Studies Working Scientifically
Semester 1 Revision The list below will assist you to check your understanding of the main concepts studied in Semester One. Work carefully through the list below and make sure that you can do what the statement says. This is not a course summary. It is a checklist for you to use to identify areas where you need extra work and a guide for your study. Macroscopic properties of matter
I can | | | Classification of matter * State and compare the characteristics of homogeneous and heterogeneous substances. * Distinguish between pure substances (elements and compounds), homogeneous mixtures (solutions) and heterogeneous mixtures. The Periodic Table * Explain the structure of the periodic table in terms of periods (1 – 7 ), Groups (1 – 18), and metals/non-metals * Describe the trends in atomic size and down a Group and across a Period. * Describe the trend in MP across period 3. |
Atomic structure and bonding
I can | | | Atomic structure * State that matter is built up from minute particles called atoms. * Write the symbols and names of the following elements: H, He, Li, Be, B, C, N, O, F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Sr, Ag, Sn, I, Ba, Pt, Au, Hg, Cd and Pb. * List the relative charges and relative masses (on the atomic mass scale) of the fundamental particles - protons, neutrons and electrons. * State that atoms have a dense positively charged nucleus (consisting of protons and neutrons) around which move negatively charged electrons. * State that an element is identified by its atomic number (Z), which is the number of protons in the nucleus and determines the number of electrons in a neutral atom of the element. *
