The Periodic Table, Elements and Compounds

Key Issues

Titles

Chapters

• A substance that is made of only one sort of atom is called an element
• All materials composed of one or more elements
• All substances are made of atoms
• CHEMICAL CALCULATIONS
• classify substances as elements (metallic or non-metallic), compounds or and mixtures and distinguish between them according to their properties
• Compounds
• demonstrate a knowledge that the Periodic Table groups together elements with similar properties, e.g. the Alkali metals as a group of reactive metals, the Halogens as a group of reactive non-metals, the Noble gases as a group of unreactive non-metals
• describe simple trends in the properties of elements within Groups (I, II,VII) and across Periods (2 and 3) of the Periodic Table
• Electronic structures of the first 20 elements in the Periodic Table
• ELEMENTS
• Elements and Atoms
• Elements are shown in the periodic table
• Elements as the 'building blocks' for all materials
• Gradual changes in the properties of elements in one group
• Groups in the Periodic Table
• INORGANIC QUALITATIVE ANALYSIS
• match up symbols and names of elements
• outline the work of Mendeleev in the development of the Periodic Table
• Periods and groups
• predict where an unfamiliar element should be placed in the series based on comparative information
• Reactions related to the electronic structure of an element
• recall the chemical symbols of elements
• relate the position of selected elements in the Periodic Table and their properties to their electronic structure
• Similarities in chemical properties of elements in the same group
• The Alkali Metals
• The connection between number of outer electrons and position in the Periodic Table
• The elements in Group 1 of the periodic table all react with non-metal elements to form ionic compounds in which the metal ion has a single positive charge
• The elements in Group 1 of the periodic table, the alkali metals, have similar chemical properties
• The elements in Group 7 of the periodic table, the halogens, have similar chemical properties
• The elements in Group 7 of the periodic table, the halogens, react with alkali metals to form ionic compounds in which the halide ions have a single negative charge
• The gradual change in properties of the elements in each group
• The groups contain elements with similar properties
• The Halogens
• THE PERIODIC TABLE
• The Periodic Table with elements in order of increasing atomic number
• The position of alkali metals, halogens, noble gases and transition metals in the Periodic Table
• The position of metals, non-metals, alkali metals, halogens and noble gases in the Periodic Table
• There are about 100 different elements
• use the Periodic Table to predict the properties of certain unfamiliar elements, limited to Groups I, II,VII and properties to relative atomic mass, atomic size, metallic and non-metallic characteristics, valency and chemical reactivity with oxygen, water
