The Periodic Table and Periodic Properties 1

Paired electrons are more reactive than unpaired electrons.

A group I metal is always more reactive then its group II neighbor.

Elements in group 8 are called the:

Alkali metals behave similar to one-another because they have 1 valence electron.

When the difference in electronegativity is very low, the bond is always polar.

Elements get bigger down a group because of

Metals are found on the _____ of the periodic table.

Elements farther to the right are smaller because they have

Bonds with electronegativity differences greater than 0.5 are polar.

When nonmetals gain electrons their size

Elements in the same group are more alike than elements in the same period.

Paired electrons in alkaline earth metals make them more stable than alkali metals.

Fluorine and Chlorine are alike because they both have 7 valence electrons.

When metals lose electrons their radius

Electronegativity is a measurement of strength of attraction for bonded valence electrons.
