    because the have different properties

    the alkali and alkaline earth metals have only up tp 2 electrons respectively

    the middle group have wat is called the d orbital which holds up to 10 plus the other 2

    the lanthanide and actinide series have another orbital called the f, but its kinda confusing for now

    also, the first two groups have a high reactivity while the others tend to stay by themselves

    hope it helps

    but it all has to do with electron orbitals
