Question

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

Explanation:

Metals tend to lose electrons to form positive ions. Rubidium is an alkali - metal and has a low ionization energy due to its large atomic size and single valence electron. Iodine is a non - metal and gains electrons. Gallium is a metal but less reactive than rubidium in losing electrons. Argon is a noble gas with a stable electron configuration and does not easily lose or gain electrons.

Answer:

C. rubidium (Rb)
