Question

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

Explanation:

• Gallium (Ga) is a metal. Metals tend to lose electrons to form positive ions.
• Iodine (I) is a non - metal and gains electrons to form negative ions.
• Argon (Ar) is a noble gas with a full valence shell and is chemically inert.
• Rubidium (Rb) is a metal but in this context, gallium is the more likely candidate among the given options as it is in a lower period (period 4) compared to rubidium (period 5) and has a more typical metallic behavior for the purpose of this basic ion - formation question.

Answer:

Gallium (Ga)
