Film summary
Witness the exciting reactions that occur when alkali metals come into contact with other substances. What does this tell us about their properties?Key facts
- The alkali metals make up Group 1 of the periodic table.
- The alkali metals are highly reactive due to only one outer electron.
- The alkali metals react quickly with water to produce an alkaline solution.
- The reactivity of the alkali metals increases as you go down the group.
Transcript
Lithium, sodium and potassium.
The group 1 elements are called the alkali metals.
Alkali Metals
Their atoms all have just one outer electron, which makes them highly reactive.
Dr Andrea Sella, University College London – "We have here the alkali metals – and I'm going to take the first – and actually the lightest …
