Question

1. which of the following elements, when combined with chlorine (cl), would most likely form an ionic compound?

carbon (c)

lithium (li)

phosphorus (p)

oxygen (o)

clear all

Explanation:

Step1: Recall Ionic Compound Formation

Ionic compounds form between metals (usually) and non - metals, where electrons are transferred. Chlorine (Cl) is a non - metal (halogen). We need to identify which of the given elements is a metal.

Step2: Classify Each Element

• Carbon (C): Non - metal (in group 14, non - metallic properties).
• Lithium (Li): Metal (alkali metal, group 1).
• Phosphorus (P): Non - metal (group 15, non - metallic).
• Oxygen (O): Non - metal (group 16, non - metallic).

Since ionic compounds are typically formed between a metal and a non - metal, and Lithium is a metal while Cl is a non - metal, Lithium will most likely form an ionic compound with Chlorine.

Answer:

B. Lithium (Li)
