Question

how does rb bond with other elements? (1 point)
○ rb gains an electron.
○ rb loses an electron.
○ rb gains two electrons.
○ rb loses two electrons.

Explanation:

Step1: Determine the valence electron of Rb

Rb (Rubidium) is in Group 1 of the periodic table. Elements in Group 1 have 1 valence electron.

Step2: Analyze electron - transfer in bonding

To achieve a stable electron configuration (similar to the noble gas configuration), Rb will lose its 1 valence electron.

Answer:

Rb loses an electron.
