  1. What does it mean when a metal is malleable?
    Show the answer

    It can be shaped by hammering or pressing. Malleable metals can be deformed by compressive force, like hammering, without cracking. Gold is famously malleable.

  2. What is a native metal?
    Show the answer

    A metal found in nature already in pure form. Native metals occur naturally in pure form, like gold nuggets, needing no smelting to be worked.

  3. What does metallurgy study?
    Show the answer

    The science of metals and how to work them. Metallurgy covers extracting metals from ores and understanding their properties and processing.
