2 The elements of the periodic table can be divided into three main categories: Metals, Non-Metals, and Metalloids.
3 Properties of MetalsMetals are good conductors of heat and electricity.Metals are shiny.Metals are ductile (can be stretched into thin wires).Metals are malleable (can be pounded into thin sheets).A chemical property of metal is its reaction with water which results in corrosion.
4 Properties of Non-Metals Non-metals are poor conductors of heat and electricity.Non-metals are not ductile or malleable.Solid non-metals are brittle and break easily.They are dull.Many non-metals are gases.Sulfur
5 Properties of Metalloids Metalloids (metal-like) have properties of both metals and non-metals.They are solids that can be shiny or dull.They conduct heat and electricity better than non-metals but not as well as metals.They are ductile and malleable.Silicon

10 6. Bohr Models representThe atom as a small positively charged nucleus surrounded by electrons.Covalent BondsPaired and unpaired valence electrons in an atom.Ionic Bonds[Default][MC Any][MC All]
11 7. The atomic number is The number of neutrons in an atom. The number of electrons in an atom.The number of protons in an atom.The number of protons and neutrons in an atom.[Default][MC Any][MC All]
12 8. The nucleus of an atomA unique number that represents the number of protons in an atom.Is the dense, positively charged mass located in the center of an atom.A particle smaller than an atom (e.g. neutron)A visual model of the most likely locations for the electrons in an atom.[Default][MC Any][MC All]
13 9. If you are given the mass number and the atomic number for an atom, how would you determine the number of neutrons?Subtract the atomic number from the mass number.Determine the number of electrons because that will tell you the number of neutrons.Determine what period the element is in.Count the number of valence electrons.[Default][MC Any][MC All]
14 10. The Lewis Structure represents The atom as a small positively charged nucleus surrounded by electrons.ProtonsNeutronsPaired and unpaired valence electrons in an atom.[Default][MC Any][MC All]
