Question

Mercedes Ele The periodic table was arranged the way it was because certain groups of elements tend to interact with members of other groups in very similar ways or exhibit very similar properties. Most (but not all) group names are associated with elements in the same column of the periodic table. Match the group names with notable properties of the group. Very Soft, Very Reactive with water A- Alkaline earth metals - # Usually form compounds in +2 oxidation state C.Noble gases The natural elemental state is diatomic molecules Very chemically intert Unexpected electronic configurations - E. Transition metals

Explanation / Answer

Alkali metals = very soft, very reactive with water

Because it contain valence electrons in outer shell.

Alkaline earth metals = usually from compounds in +2 oxidation state

Be2+, Mg2+, Ca2+ etc...

Halogens = natural elemental state is diatomic

Cl2, Br2, I2

Noble gases = very chemically inert

Because it does not have any valence electrons in the outer shell.

Transition metals = unexpected electronic configuration
