Group 1 – The Alkali Metals
Group 1 are metals that are found on the left hand-side of the periodic table. They are also known as the alkali metals and are highly reactive. Through this tutorial we will be exploring the physical and chemical properties of the alkali metals and the trends through group 1.
Physical properties of the alkali metals
- The alkali metals are soft solids at room temperature and can easily be cut with a knife.
- They also have low densities which means that these elements can float on water.
- They have low melting and boiling points; this decreases as you go down the group.
Chemical properties of the alkali metals
- Atoms of group 1 elements react in the same way. All the elements in group 1 are highly reactive, have the same properties and react in the same way this is because all the alkali metals have a single electron in their outermost shell. When atoms of group 1 elements react, they each lose one electron forming a positively charged ion.
