Question

Which pair of elements would most likely combine to form a salt?

Na and C

N and F


Cs and I

I and F

Answer 1

Cesium (Cs) and Iodine (I) would most likely combine to form a salt called (Option C) Cesium iodide (CsI).

Step-by-step explanation:

The pair of elements that would most likely combine to form a salt is (Option C) Cs and I (Cesium and Iodine).

A salt is an ionic compound formed when a metal cation combines with a non-metal anion. Cesium (Cs) is a metal and Iodine (I) is a non-metal. When Cs and I combine, they form an ionic compound called Cesium iodide (CsI).

This is because Cs loses an electron to become Cs+ and Iodine gains that electron to become I-. The Cs+ cation is attracted to the I- anion due to their opposite charges, resulting in the formation of CsI.
