8 Groups of The Periodic Table NonmetalsAlkali MetalsAlkaline Earth MetalsTransition MetalsMetalsMetalloidsHalogensNoble GasesRare Earth Metals

Properties of The Elemental Groups Nonmetals
high ionization energies High electronegativities Poor thermal conductors Poor electrical conductors
04/12/2023Russell Godman
Alkali Metals Lower densities than other metals One loosely bound valence electron Largest atomic radii in their periods Low electronegativities Highly reactive
04/12/2023Russell Godman
Alkaline Earth Metals Two electrons in the outer shell Two electrons in the outer shell Low electronegativities Readily form divalent cations.
04/12/2023Russell Godman
Transition Metals Low ionization energies Positive oxidation states High melting points High boiling points High electrical conductivity Malleable
04/12/2023Russell Godman
Metals Solids at room temperature (except
mercury) High melting points High densities Low electronegativities Malleable Thermal conductors Electrical conductors
04/12/2023Russell Godman
Metalloids Electronegativities between those of
metals and nonmetals Ionization energies between those of
metals and nonmetals Possess some characteristics of
metals/some of nonmetals Reactivity depends on properties of
other elements in reaction
04/12/2023Russell Godman
Halogens Very high electronegativities Seven valence electrons (one short of a
stable octet) Highly reactive, especially with alkali
metals and alkaline earths
04/12/2023Russell Godman
Noble Gases Fairly nonreactive Complete valence shell High ionization energies Very low electronegativities Low boiling points (all gases at room
temperature)
