Periodic Table: Key Properties of Metals, Nonmetals, and Metalloids

Alkali metals

Metal, forms 1+ ions, extremely reactive

Alkali metals

Metal, loses 1 electron reacts aggressively with water

Alkaline earth metals

Metals, highly reactive, 2+ ions

Alkaline earth metals

Metals, loses 2 electrons, reacts with water, but not as strongly as alkali

Halogens

Nonmetals, solids, liquids, gases at room temp, -1 charge in ions

Halogens

Nonmetals, very reactive and gain 1 electron

Noble gases

Nonmetals, gases, unreactive

Transition metals

Ductile, Malleable, high boiling and melting points, forms multiple positive ions, useful as catalysts.

Inner transition metals

Paramagnetic, silver, extremely reactive, short full lives, but long half lifes, multiple positive ions

Oxygen group

Nonmetals and metalloids, often gains 2 electrons

Oxygen group

Forms 2- ions, Becomes more metallic further down the group

Boron, Carbon, Nitrogen groups

Metals, nonmetals, and metalloids, increase in metallic property further down groups, less reactive, and tends to share electrons
