Ionic and Covalent Compounds

Ionic and Covalent Compounds Q. What is a compound? How is it different from an element? A compound is more than one element. Two types of compounds exist: Ionic and covalent compounds.

Properties of Ionic Compounds Atoms joined chemically with strong ionic bonds (e- are transferred). Are composed of metals and nonmetals. Have high melting points.

Properties of Covalent Compounds Atoms joined chemically with weaker covalent bonds (e- are shared). Are composed only of nonmetals. Have lower melting and boiling points.

Ionic and Covalent Compounds Both ionic and covalent compounds can be represented using Bohr models or Lewis electron dot structures. Q. Why do atoms combine? A. They “want” to be stable, that is, have a full outer shell.

Is it an Ionic or Covalent Bond? Does the compound contain a metal cation? Yes No Does the metal have more than one possible combining capacity? Compound is a binary molecule, therefore, we use prefixes to name the compound. No Yes Do NOT use Roman Numerals to name the compound Use the stock system of naming Does the compound contain a complex ion? Yes No The compound is a Ternary Ionic Compound The compound is a Binary Ionic Compound
