Question

name the following compound
agcl

question 3

what is the correct formula for chromium (ii) fluoride?

Explanation:

Step1: Name the compound AgCl

Ag is silver, Cl is chloride. For binary ionic compounds (metal + non - metal), we name the metal first and then the non - metal with the suffix -ide. So AgCl is silver chloride.

Step2: Find the formula for Chromium (II) fluoride

Chromium (II) has a charge of \(Cr^{2+}\), fluoride is \(F^{-}\). Using the criss - cross method (the magnitude of the charge of one ion becomes the subscript of the other ion), for \(Cr^{2+}\) and \(F^{-}\), the formula is \(CrF_{2}\)

Answer:

1. Silver chloride
2. \(CrF_{2}\)
