Atoms and Metals, Nonmetals and Metalloids Practice

Master atoms, metals, nonmetals, and metalloids! Practice identifying elements and atomic structure.

Use the Periodic Table below to identify each element as either a metal, nonmetal or metalloid. Using the periodic table above, decide whether the element is a metal, nonmetal or metalloid. Metal Mn Au Na Tc Al Pb K Ca Nonmetal H O I Se Rn P S C Metalloid Te As Sb Si Match the vocabulary word with the definition. These are words that you need to understand to identify metals, nonmetals and metalloids. Ductile Can be pulled into a thin wire. Malleable Can be be pressed into thin sheets. Luster The way that light reflects off of an object. Metallic Shiny Non metallic Not Shiny - Dull Brittle Can break easily Good conductor Allows heat and electricity to pass through easily Poor Conductor Does NOT allow heat and electricity to pass through easily Semi-Conductor Allows some heat and electricity to pass through Semi-Metallic Some are shiny and some are dull What are the two subatomic particles inside the nucleus? (Choose the two correct answers) protons neutrons electrons Which subatomic particle is located in the electron cloud level? proton neutron electron Which subatomic particle identifies an atom? proton neutron electron The periodgives us the number of energy levels an atom will have. There are a total of sevenperiods.The groups gives us the number of valence electrons the atom will have. There are a total of eighteen groups, with group onebeing the mostreactive and group eighteenbeing the least reactive. Fill in the blanks.
