Answer 1

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 found in Group 1 of the periodic table, which means it has one electron in its outermost shell. Alkali metals readily lose this one electron to form positive ions (cations) with a charge of +1.

In contrast, argon (Ar) is a noble gas and does not typically lose or gain electrons, gallium (Ga) can lose electrons but is less likely than rubidium, and iodine (I) tends to gain electrons to form negative ions.
