Fixed charge metal naming - Start: Is the compound ionic? → Yes,What type of metal? → Alkali/Alkaline Earth,What is the anion? →Non-metal, Rule: Name metal + anion with -ide ending (e.g., NaCl = Sodium chloride). Non-metal. What is the anion? → Non-metal.What is the anion? → Non-metal.What is the anion? → Non-metal.What is the anion? → Non-metal.What is the atal.What is the anion? → Non-metal., Variable Charge Metals (e.g., Transition Metals) Naming - Start: Is the compound ionic? → Yes, What type of metal? → Transition/Inner Transition/p-block Metal, Can the metal have multiple charges? → Yes.Find the charge by balancing with the anion., Use Roman numeral for the metal charge (e.g., FeCl₃ = Iron (III) chloride), Octet Rule - Most elements tend to bond in such a way that they have eight electrons in their valence shell (an octet), achieving a stable electron configuration similar to that of noble gases., Empirical Formula - Represents the simplest whole-number ratio of elements in a compound., Molecular Formula - Shows the actual number of atoms of each element in a molecule of the compound., Aufbau Principle - electrons fill orbitals starting from the lowest energy level before moving to higher ones., Hund's Rule - Hund's Rule states that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up., Pauli Exclusion Principle - no two electrons in an atom can have the same set of four quantum numbers., Metals - Metals are typically found on the left side and center of the periodic table, and tend to lose electrons to form ions., Non-Metals - Non-metals are typically found on the right side of the periodic table, and tend to gain electrons to form ions., Metalloid - Metalloids are typically found on the border between metals and non-metals in the periodic table, and exhibit some properties of metals and some properties of non-metals., Atomic Radius - Atomic radius increases as you move down a group, decreases as you move across a period, Ionization Energy - decreases as you move down a group, increases because the nucleus,
