Key definitions in ionic bonding Flashcards
Cation - A positive ion - “pawsitive”
Anion - A negative ion
Ionic bond - A strong electrostatic attraction between positive and negative ions
Binary ionic bond - A binary ionic compound is composed of ions of two different elements like sodium iodide and sodium chloride. A non binary ionic bond is NaNO₃.
Monatomic ion - A monatomic ion is a ion that consists of only one atom “Monobrow”
Polyatomic ion - A polyatomic ion is an ion that consists of two or more atoms such as sulphate.
Ionic lattice - An ionic lattice is a regular repeating structure consisting of alternating cations and anions. Also 3D.
Bonding of ionic compound - Electrostatic attraction between cations and anions. Ionic bond
Structure of ionic compound - ionic lattice
Empirical formula - Simplest ratio of atoms/element
Lattice enthalpy - The enthalpy when breaking down 1.00 mol of an ionic compound into its gaseous ions.
Volatility - Rate of evaporation
Solubility - How soluble it is
Ammonium - NH₄+
Hydroxide - OH-
Hydrogen carbonate - HCO₃-
Sulphate - SO₄2-
Nitrate - NO₃-
Carbonate - CO₃-
Phosphate - PO₄3-
