  • Which element is an alkali metal?
    An alkali metal is any element in group 1A of the periodic table, such as lithium, sodium, potassium, rubidium, cesium, or francium.
  • What is a common substance that alkali metals react vigorously with?
    Alkali metals react vigorously with water, producing heat and often explosive reactions.
  • What do all alkali metals have in common?
    All alkali metals have one valence electron, are highly reactive, have low densities, and are found in group 1A of the periodic table.
  • What are the key properties of alkali metals?
    Alkali metals are highly reactive, have low ionization energies, and are typically found as +1 cations in nature.
  • What are the properties of alkali metals?
    Alkali metals are malleable, have low densities, low melting and boiling points, and are highly reactive.
  • Why are alkali metals so reactive?
    Alkali metals are so reactive because they have a single valence electron that is easily removed due to low ionization energy.
  • Name an alkali metal.
    Lithium, sodium, potassium, rubidium, cesium, and francium are alkali metals.
  • What determines the reactivity of an alkali metal?
    The reactivity of an alkali metal is determined by its single valence electron and low ionization energy.
  • Which element is classified as an alkali metal: Rb, Sr, Zr, or Cl?
    Rb (rubidium) is classified as an alkali metal.
  • An alkali metal will most readily react with which substance?
    An alkali metal will most readily react with water, producing a highly exothermic and often explosive reaction.
