Cheat Sheet
- Electronegativity and Bond Type -
Understanding electronegativity differences is key: a ΔEN ≥ 1.7 typically indicates ionic bonding, while ΔEN < 1.7 suggests covalent bonding. Use the "FONCl BrISCH" mnemonic (Fluorine, Oxygen, Nitrogen, Chlorine, Bromine, Iodine, Sulfur, Carbon, Hydrogen) to rank elements by electronegativity. This concept is often tested in any ionic and covalent bonding quiz, so practice with examples like NaCl (ionic) and H₂O (polar covalent).
- Formation of Ions and Lattice Energy -
Ionic bonding practice tests frequently ask you to predict cations and anions: metals lose electrons to form cations, nonmetals gain to form anions. Lattice energy measures the strength of an ionic solid, and a higher charge or smaller ionic radius increases that energy (e.g., MgO vs. NaCl). Remember the Born - Haber cycle from university chemistry resources for calculations.
- Polar vs. Nonpolar Covalent Bonds -
Covalent bonding questions often focus on bond polarity, determined by ΔEN: if ΔEN is between 0.4 and 1.7, bonds are polar; below 0.4, they're nonpolar. Draw Lewis structures and calculate dipole moments to visualize charge separation, like in CO₂ (nonpolar overall) versus HCl (polar). Practice with molecules like CH₄ and NH₃ to solidify your understanding before the quiz.
- VSEPR and Molecular Geometry -
Memorize key electron-pair geometries (linear, trigonal planar, tetrahedral) using the VSEPR model to predict shapes and bond angles. For example, water's bent shape (104.5°) arises from two lone pairs on oxygen, teaching you how shape influences polarity. This concept underpins many covalent and ionic bonding quick check questions on molecular geometry effects.
- Compounds with Both Ionic and Covalent Bonds -
Which of the following contains both ionic and covalent bonding? Classic examples include Ca(NO₃)₂ and NH₄Cl, where polyatomic ions are covalently bonded internally but ionically bonded to counterions. Review the structures and charges of common polyatomics (e.g., SO₄²❻, PO₄³❻) from official educational sites to ace this section of the quiz.
