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