Periodic Table basics. Task 1: Read the information on slides 2 to 5 and then answer the questions on slide 6. v The Periodic Table tells us about elements. v The elements are arranged in order in the Periodic Table. v An element is made of one type of atom only e. g. magnesium v A compound is made of two or more different atoms joined together e. g. water v The horizontal rows are called periods. v The columns going down are called groups. v There is a zigzag line dividing the metals from the non-metals. v Some groups have a collective name for the elements.

There is a zig zag line that separates the metals from the non-metals. The metals are on the left.

The horizontal rows are called periods. The vertical columns are called groups.

Group 1 is called the alkali metals. Group 2 is called the alkaline earth metals The block between groups 2 and 3 is called the transition metals Group 7 is called the halogens. Group 0 is called the noble gases.

All substances are made of tiny ________ called atoms. Elements are the simplest substances and are made of only _____ type of particle. The elements are arranged in _____ in the Periodic Table. The vertical columns in the Periodic Table are called ______. Each horizontal ______ in the Periodic Table is called a period. Compounds are made of more than one type of _____. Water is a _______. The properties of a compound can be different from the properties of its _______.

Task 3: Using either the ‘draw’ tool or a printed copy Draw the zigzag line on the periodic Table Label and colour the alkali metals in blue; Label and colour the alkaline metals in green; Label and colour the transition metals in yellow; label and colour the halogens in purple; Label and colour the noble gases in red.

Each element has its own symbol. There are rules for the symbols of the elements: Each element has its own symbol that starts with a capital letter E. g. potassium has the symbol K Where a symbol has two letters the second one is always lower case E. g. Lithium has the symbol Li. Don’t worry about the numbers at this stage!!

Task 4: Use your periodic Table to complete the following task.
