Why are alkali metals known as Group 1 metals and how did we prove this?
When Group 1 elements react with water, they produce alkaline metal hydroxides
How are Group 1 metals different to common metals?
They are soft, shiny, highly reactive and have low melting points and densities
How does lithium react in water?
Lithium floats, fizzes and disappears, forming lithium hydroxide and releasing hydrogen gas
How does sodium react in water?
Sodium melts into a ball, then disappears, forming sodium hydroxide and releasing hydrogen gas
How does potassium react in water?
