Which element would most likely lose electrons to form postive ions when bonding with other elements? 1.argon(Ar) 2.gallium(Ga) 3.lodine.(i) 4.rubidium(Rb)

1 answer

The element that would most likely lose electrons to form positive ions when bonding with other elements is rubidium (Rb).

Rubidium is an alkali metal, which means it has one electron in its outermost shell. Alkali metals tend to lose this single electron to achieve a stable electronic configuration, resulting in the formation of positive ions (cations) with a +1 charge.

In contrast, argon is a noble gas and is generally unreactive, while gallium and iodine are less likely to readily lose electrons to form positive ions compared to rubidium.
