  • How many valence electrons do alkaline earth metals have, and do they typically form cations or anions?
    Alkaline earth metals have 2 valence electrons and typically form cations by losing these electrons.
  • Which is a characteristic of the alkaline earth metals?
    Alkaline earth metals are found in group 2A, have 2 valence electrons, and generally form ionic bonds with nonmetals.
  • Alkaline earth metals have how many valence electrons?
    Alkaline earth metals have 2 valence electrons.
  • What is a characteristic that alkaline earth metals do NOT have?
    Alkaline earth metals do NOT typically form anions; they usually form cations by losing electrons.
  • What are some properties shared by alkaline earth metals?
    Alkaline earth metals are solid at high temperatures, have strong metallic bonding, and generally form ionic compounds except for beryllium, which can form covalent bonds.
  • What is a characteristic property of alkaline earth metals regarding their valence electrons and ionic charge?
    A characteristic property is that they have 2 valence electrons and form cations with a +2 charge.
  • What is a characteristic physical property of alkaline earth metals related to their state and bonding?
    Alkaline earth metals are solids at high temperatures and have strong metallic bonds due to their effective nuclear charge.
  • Why are alkaline earth metals called 'alkaline' and 'earth'?
    They are called 'alkaline' because they help make basic solutions, and 'earth' because they remain solid at high temperatures.
  • Which alkaline earth metal is radioactive and difficult to predict in chemical behavior?
    Radium is radioactive and its chemical behavior is hard to predict.
  • How does the effective nuclear charge in alkaline earth metals affect their metallic bonding?
    A higher effective nuclear charge makes it harder to remove electrons, resulting in stronger metallic bonding and higher melting points.
