What are valence electrons?
They determine the shape of an element
Elements with metalloid characteristics
Positively charged electron
The electrons in an atom's outermost shell
Periods on the periodic table:
up and down (columns)
left to right (rows)

How is the periodic table organized?
By atomic number (protons), similar properties, valence electrons, groups, atomic mass
Similarly sounding elements are placed nearby
Elements are listed in alphabetical order
Metals, metalloids, and nonmetals are placed in a pattern that makes a pretty picture

Germanium (Ge)
Tellurium (Te)
Aluminum (Al)
Antimony (Sb)
