Atoms of one element cannot be converted into atoms of another element. Atoms of an element are identical and are different from atoms of any other element. 16 Matter MATTER PURE SUBSTANCE (homogeneous) ELEMENTS (listed in the periodic table; there are about 120 elements) MIXTURE (may be heterogeneous or homogenous) COMPOUNDS (2 or more elements combined in a unique ratio, there are about 15 x 106) 17 Occurrence of Elements in Nature • Only 6 occur normally as atoms: He, Ne, Ar, Kr, Xe, Rn ‘Noble or Inert Gases’ Identify these on the periodic table • Other elements occur as molecules: H2, N2, O2, F2, Cl2, Br2, I2 all diatomic in nature Identify these on the periodic table • Other elements may have larger molecules: S8 • Other materials have infinitely large aggregates of atoms: C, Cu, Fe, Ag 18 Learning Outcomes: • By the end of this lecture, you should: – know the assessment schedule for CHEM1001 – know who to contact if you have questions or worries – know about the course textbook – know that you should be checking your university email regularly – be able to explain what an atom is – be able to find elements on the Periodic Table and label their period and group numbers – be able to complete the worksheet (if you haven’t already done so….) 19 Questions to complete for the next lecture: • Fill in the gaps in the following statements: 1) An …………. is a substance which cannot be broken down into simpler component substances. 2) An ………… is the smallest possible unit of an element. 3) A ………… contains two or more atoms 4) A ……….. contains two or more different elements. 20 Questions to complete for the next lecture: • Using the Periodic Table on the worksheet, fill in the gaps in the table below: Group Period 17 1 2 12 5 4 6 Symbol of element Na Ca Name of element Atom number 53 11 14 21
