Elements in groups 1 and 2 and in groups 13 through 18 are called?
Elements in groups 1 and 2 are called alkali and alkaline earth metals, respectively. Elements in groups 13 through 18 are known as the boron group, carbon group, nitrogen group, chalcogens, halogens, and noble gases.
How is boron different from other elements in group 13?
Boron is the only element in group 13 that is a metalloid, meaning it shares properties of both metals and nonmetals. It has a unique structure due to its small atomic size and high ionization energy compared to its group members. Boron also forms covalent compounds instead of ionic compounds like other group 13 elements.
