members of which group easily lose an electron to form a +1 cation?\n○ halogens\n○ alkaline earth metals\n○ noble gases\n○ alkali metals

Answer

Brief Explanations:

Alkali metals have one valence - electron. They easily lose this single electron to achieve a stable noble - gas electron configuration and form a +1 cation. Halogens gain an electron to form anions, alkaline earth metals lose two electrons to form +2 cations, and noble gases are stable and do not easily lose or gain electrons.

Answer:

D. alkali metals
