Reactivity increases, lower melting and boiling points, atomic mass increases
What is the reaction between a group 1 element and water?
metal + water -> metal hydroxide + hydrogen
What is the reaction between a group 1 element and chlorine?
metal + chlorine -> metal chloride
What is the reaction between a group 1 element and oxygen?
