  • Alkaline Earth Metals
    Elements in group 2a, including beryllium, magnesium, calcium, strontium, barium, and radium.
  • Reducing Agents
    Substances that donate electrons to another substance, reducing it.
  • Metal Oxide
    Compounds formed when metals react with oxygen, typically basic in nature.
  • Barium Peroxide
    A compound formed by barium and oxygen with a peroxide ion, where oxygen has a charge of minus 1.
  • Peroxide
    An ion where oxygen has a charge of minus 1, often forming compounds with metals.
  • Ionic Halides
    Compounds formed by the reaction of alkaline earth metals with diatomic halogens.
  • Amphoteric
    A substance that can act as both an acid and a base depending on the reacting compound.
  • Thermal Decomposition
    A chemical reaction where a compound breaks down into simpler substances when heated.
  • Carbonate Compounds
    Compounds containing the carbonate ion, which decompose to form metal oxides and CO2.
  • Basic Ion
    An ion that increases the pH of a solution, typically hydroxide ions produced by metal oxides.
  • Limestone
    A sedimentary rock primarily composed of calcium carbonate, formed from calcium oxide.
  • Valence Electron
    An outer shell electron that participates in chemical bonding.
  • Group 1a
    Elements known as alkali metals, which have one valence electron.
  • Polyatomic Ion
    An ion composed of two or more atoms covalently bonded, acting as a single unit.
  • Hydroxide Ion
    A negatively charged ion (OH-) that makes solutions basic.
