Question

question 7 of 10 why do metals tend to lose electrons to form positive ions? a. the positive ions that are formed when metals lose electrons are more reactive than the neutral metals. b. they hold on tightly to electrons. c. they conduct electricity, which makes them lose their electrons. d. a metal atom loses its few valence electrons to form a full octet.

Explanation:

Metals have few valence - electrons. By losing these valence - electrons, they can achieve a stable electron configuration with a full outer shell (usually an octet). This is the driving force for them to form positive ions. Option A is incorrect as positive ions are not necessarily more reactive. Option B is wrong because metals do not hold on tightly to electrons. Option C is incorrect as conductivity is not the reason for losing electrons to form positive ions.

Answer:

D. A metal atom loses its few valence electrons to form a full octet.
