Question

why ate group one metals so reactive and what are they called​

Answer 1

Explanation:

Group 1 metals are called Alkaline earth metals. There are so reactive because all elements want to be stable. If the elements want to be stable then there electronic configuration has should be 8 electrons should be present. These Group 1 elements have to gain or lose 1 electron in there outer most shell. If these elements want to gain an electron, there are so many elements that want to lose a electron to get stability. That is why These are more reactive.
