Question

1. members of this family are less reactive metals and do not have identical outer electron configurations. they are shiny and good conductors of heat and electricity. (0.5 points) * actinides transition metals boron group alkaline earth metals lanthanides nitrogen group noble gases alkali metals halogens carbon group oxygen group

Explanation:

Transition metals are less reactive metals. They have variable outer electron configurations (due to the involvement of d - orbitals in bonding). They are shiny (lustrous) and good conductors of heat and electricity. Actinides are radioactive and have different properties. Boron group has non - metal (boron) and metals with different reactivity. Alkaline earth metals have similar outer electron configurations (ns²). Lanthanides have similar chemical properties due to similar outer electron configurations (involved in f - block). Nitrogen group, noble gases, alkali metals, halogens, carbon group, and oxygen group do not match the description of less reactive metals with non - identical outer electron configurations, shiny, and good conductors.

Answer:

Transition metals
