Question

give the chemical formula and chemical name that would result from the ionic bond between the given elements. lithium and iodine. chemical formula. chemical name.

Explanation:

Step1: Determine ion charges

Lithium (Li) is in Group 1, so it forms a $Li^+$ ion with a +1 charge. Iodine (I) is in Group 17, so it forms an $I^-$ ion with a - 1 charge.

Step2: Write the chemical formula

To form a neutral compound, the charges must balance. Since the charges of $Li^+$ and $I^-$ are equal in magnitude but opposite in sign, the chemical formula is LiI.

Step3: Name the compound

The name of the compound formed from a metal (lithium) and a non - metal (iodine) is lithium iodide.

Answer:

Chemical Formula: LiI
Chemical Name: lithium iodide
