Cheat Sheet
- Atomic Number, Mass Number, and Isotopes -
The atomic number (Z) equals the number of protons and defines the element, while mass number (A) sums protons and neutrons. Recognizing Z and A is essential for atomic structure questions, element structure quizzes, and every atomic structure quiz. For example, carbon-12 and carbon-14 share Z but differ in A, a basis for radiometric dating.
- Electron Configuration Principles -
Use the Aufbau principle (fill lowest energy orbitals first), Pauli exclusion principle (two electrons max per orbital), and Hund's rule (maximize unpaired spins) to write electron configs accurately. For example, oxygen's 1s² 2s² 2p❴ notation is a staple on the atomic structure quiz, as outlined in MIT OpenCourseWare.
- Periodic Trends: Radius, Ionization Energy & Electronegativity -
Across a period, atomic radius decreases while ionization energy and electronegativity increase, peaking at fluorine, and the opposite trend occurs down a group. These patterns are frequently tested on a periodic table quiz, and tools like the mnemonic "FONClBrISCH" help recall electronegativity order (ACS).
- Chemical Bonding Basics -
Ionic bonds form via electron transfer (e.g., NaCl), covalent bonds via sharing (e.g., H₂), and metallic bonds via delocalized electrons; understanding these types is crucial for any chemical bonding quiz. Applying the octet rule clarifies bonding patterns and predicts molecular shapes, as described by the American Chemical Society.
- Stoichiometry & Molar Mass Calculations -
Use molar mass (g/mol) and Avogadro's number (6.022×10²³ mol❻¹) to interconvert grams, moles, and particles (e.g., 18.02 g H₂O = 1 mole = 6.022×10²³ molecules). Mastery of these stoichiometry skills is essential for atoms and molecules quiz problems and general chemical calculations (Khan Academy).
