explain group one metals reaction in water
The metal hydroxide will form and will be alkaline in solution. Universal indicator turns purple and alkaline solutions. The hydrogen gas can be tested for by using a lit splint. It will give a squeaky pop if hydrogen is present. It has a lower density than water So it will float
explain what happens when group one metals react
When group one metals react they lose one electron. As you go down group one the elements are more reactive so they lose that one electron more easily as the atom becomes larger. The outer shell electron gets further away from the nucleus weakening the forces of attraction.
