Help your students understand how the Periodic Table of Elements is organized! Students will have to correctly label the different parts of the periodic table using the following words: actinides, alkali metals, alkaline earth metals, halogens, lanthanides, metalloids, metals, noble gases, nonmetals, and transition metals. Answers are included! $
Lithium. Lithium (from Greek lithos 'stone') is a chemical element with symbol Li and atomic number 3. It is a soft, silver-white metal belonging to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable. For this reason, it is typically stored in mineral oil.
The Alkali Metals I wanted to display all the key points about each group of elements, in a way that was both clear and engaging for the pupils – as a consequence, the information presented is relatively basic, so that it’s accessible for as many of the year groups as possible. I also tried to include some information regarding uses of the elements or compounds containing them, in order to make it relevant and pique the pupils’ interest.
