Question

use the periodic table to answer the question. covalent and ionic bonding. which element would most likely lose electrons to form positive ions when bonding with other elements? (1 point) rubidium (rb) iodine (i) gallium (ga) argon (ar)

Explanation:

Step1: Recall periodic - table trends

Metals tend to lose electrons to form positive ions. Metals are located on the left - hand side and in the middle of the periodic table. Non - metals tend to gain electrons and noble gases are stable.

Step2: Identify the type of each element

Rubidium (Rb) is an alkali metal in Group 1. Iodine (I) is a non - metal in Group 17. Gallium (Ga) is a metal in Group 13. Argon (Ar) is a noble gas in Group 18.

Step3: Determine the most reactive metal for losing electrons

Among these, alkali metals are the most reactive metals in losing electrons. Rubidium is an alkali metal and is more likely to lose electrons compared to gallium.

Answer:

rubidium (Rb)
