Question

which element would most likely lose electrons to form positive ions when bonding with other elements? (1 point) rubidium (rb) gallium (ga) argon (ar) iodine (i)

Explanation:

Metals tend to lose electrons to form positive ions. Rubidium is an alkali - metal, gallium is a metal but less reactive than alkali - metals. Argon is a noble gas and is stable with a full outer - shell, so it doesn't easily lose electrons. Iodine is a non - metal and tends to gain electrons. Among these, rubidium, being an alkali metal, has the greatest tendency to lose its outermost electron due to its low ionization energy.

Answer:

rubidium (Rb)
