Where are the most reactive metals group located?

The column at far left side of the table-alkali metals (1A)

Elements are arranged on the periodic table by

their atomic number and properties

A=P=E M-A=N APE stands for:

Atomic # = # of Protons = # of Electrons

When comparing metals to nonmetals, metals tend to have

higher melting point and greater conductivity than nonmetals

A neutral atom can be described as having

an equal number of protons and electrons

Where is most stable element group located?

The column at far right side of the table- noble gases (8A)

A=P=E M-A=N M-A=N stands for:

Mass # - Atomic # = # of Neutrons
