Deduce the chemical formula and structure for the ionic compounds containing the following elements: Beryllium and chlorine, Lithium and chlorine, Calcium and oxygen, Sodium and sulfur.
Understand the Problem
The question is asking for the chemical formulas and structures of ionic compounds formed by specific pairs of elements. This involves knowledge of chemical bonding and valency of the elements mentioned.
Answer
BeCl2, LiCl, CaO, Na2S
The formulas are BeCl2, LiCl, CaO, and Na2S.
Answer for screen readers
The formulas are BeCl2, LiCl, CaO, and Na2S.
More Information
Ionic compounds are formed when metals transfer electrons to non-metals, resulting in cations and anions that depend on each element’s valence shell.
Tips
A common mistake is not balancing the charges, which is crucial to obtaining the correct formula.
