Chemical Bonding & Molecular Structure Cheatsheet

Cheat Codes & Shortcuts

  • Chemical Bond: Force that holds atoms together in compounds.
  • Covalent Bond: Sharing of electron pairs (nonmetals).
  • Ionic Bond: Transfer of electrons, forms ions (metal & nonmetal).
  • Lewis Structure: Dots visualize valence electrons & bonds.
  • Octet Rule: Atoms tend to have 8 electrons in their valence shell.
  • Coordinate Bond: Both electrons in bond come from one atom.
  • VSEPR Theory: Predicts shapes using electron repulsion.
  • Hybridization: Mixing of atomic orbitals—sp, sp2, sp3.
  • Molecular Polarity: Based on electronegativity difference and shape.
  • Bond Order: Number of chemical bonds between two atoms.

Quick Reference Table

Type Description / Formula Example / Note
Ionic Bond Electron transfer, forms ions NaCl: Na+, Cl-
Covalent Bond Electron sharing between atoms H2O: O shares with H
Lewis Structure Dots for valence electrons O2 has double bond
Hybridization Merging atomic orbitals CH4: sp3
VSEPR Shapes Geometry from electron repulsion CO2: linear
Bond Order (No. bonds)/(No. positions) O2: order = 2

Advice

Step 1: Write Lewis dot structure to count electrons.

Step 2: Use VSEPR to determine molecular geometry.

Step 3: Assign bond order for strength/length prediction.

Step 4: Check for hybridization: sp, sp2, sp3 based on groups attached.

Step 5: Use electronegativity to assess polarity.

Chemical Bonding Quick Tips

  • Ionic bond: Large electronegativity difference.
  • Covalent bond: Small electronegativity difference.
  • Octet rule: Applies to main group elements; exceptions: H, B, Be, transition metals.
  • Hybridization: Count number of electron groups—2: sp, 3: sp2, 4: sp3.
  • VSEPR: Predict shape from total electron pairs (lone + bond).
