Question

Compare and contrast group 1a element and group 2a elements

Answer 1

Group 1A are elements with extremely strong metallic character, group 2A elements are comparatively weaker. This is due to 1 electron in their s orbital which can be given easily by the 1A elements to get stabilized but 2A elements have 2 electrons in their s orbital which is maximum number and therefore they are highly stable therefore they don't want to give their electrons so less met.
