Metals location
Left side of periodic table
The elements on the left side of the periodic table that are typically shiny solids that conduct heat and electricity well and are malleable and ductile
Metals
Elements with properties opposite those of metals, including poor conductivity of heat and electricity
Nonmetals
Elements along the border between metals and Nonmetals in the periodic table
Metalloids
Main group elements/representative elements
Elements in groups 1,2,13-18 and are most abundant
Transition metals
Elements in groups 3-12
Noble gases
