Question

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

Explanation:

Rubidium (Rb) is an alkali metal in Group 1 of the periodic table. Alkali metals have one valence electron. To achieve a stable electron configuration (similar to the noble gas configuration), they tend to lose one electron. So, Rb loses an electron when bonding with other elements.

Answer:

B. Rb loses an electron.
