Question

how does rb bond with other elements? (1 point)

○ rb gains two electrons.

○ rb gains an electron.

○ rb loses an electron.

○ rb loses two electrons.

Explanation:

Rubidium (Rb) is an alkali metal with one valence electron. To achieve a stable electron configuration (like a noble gas), it tends to lose its single valence electron. This is because alkali metals have low ionization energy for their valence electron, making it easier to lose one electron rather than gain electrons (which would require a high electron affinity, not typical for metals). So Rb loses an electron when bonding.

Answer:

C. Rb loses an electron.
