Metals, Nonmetals, and Metalloids at Periodic-Table Depth
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Metals, nonmetals, and metalloids occupy distinct regions of the periodic table, with metalloids forming a staircase boundary between the other two.
Show
Silicon sits along that staircase and conducts moderately, unlike aluminum's strong metallic conductivity or sulfur's poor nonmetal conductivity nearby.
Watch for
This is the same three-way split from Chem 0075, taught again here at table-position depth rather than as new material.
