Unlike ionic bonds, covalent bonds involve the sharing of electrons rather than transfer. Bond Strength: Covalent bonds can vary in strength, with multiple bonds (double, triple) being stronger than single bonds. Molecular Shapes: The geometry of molecules formed by covalent bonds infl
ding to partial charges (e.g., H₂O, NH₃). Molecular Geometry and Bond Polarity The shape of molecules influences their physical properties. Electronegativity differences determine bond polarity. VSEPR theory helps predict molecular shapes. The Role of the Answer Key
hed names. Indicate the charge if necessary: For transition metals or metals with multiple oxidation states, include Roman numerals. Examples: | Compound | Name | Explanation | |------------|--------|--------------| | NaCl | Sodium chloride | Sodium (Na) cation, chloride (Cl⁻) anion | |
Always double-check the number of atoms and match them with the correct prefixes. Remember that the first element's prefix "mono-" is often omitted. Practice with a variety of formulas to develop fluency. Use visual aids,
properties such as melting point, solubility, electrical conductivity, and hardness; ionic compounds tend to have high melting points and conduct electricity when molten or dissolved, while covalent compounds g
