Study Notes
Ionic Compounds and Formulas
- Calcium bromide is represented by the chemical formula CaBr2.
- The chemical formula for calcium phosphide is Ca3P2.
- The formula for the polyatomic ion sulfate is SO4^2−.
Ionic Charges and Properties
- Gaining electrons results in a negatively charged ion called an anion.
- A sodium ion (Na+) has a charge of 1+, indicating it has lost one electron.
- Simple cations, which are monatomic cations with a single charge, are named using their elemental name followed by "ion" (e.g., Na+ is the sodium ion).
Specific Ions and Their Names
- The ion in which nitrogen has a 3− charge is known as nitride (N3−).
- The lithium cation is correctly paired with the symbol Li+.
- The halogens typically form ions with a charge of 1−.
Common Compounds and Their Formulas
- Sodium bicarbonate is composed of Na+ and HCO3−, with the formula NaHCO3.
- Magnesium chloride is represented by MgCl2.
- Calcium fluoride is expressed as CaF2.
Definitions of Ion Types
- Cations formed from halogens generally carry a charge of 1− and are named by adding the suffix "ide" (e.g., F− is called fluoride).
