Grouping describes the behavior of elements. Different groups have different properties.
by their atomic number in the periodic table by grouping the elements on the periodic table
true
Noble Gases
Reactivity is associated with position. Chemical properties of element can be determined from its position.
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
By grouping the elements on the Periodic Table.

Periodic Table - Or Table of Reactivty
Yes
The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.

Reactivity is associated with position. Chemical properties of element can be determined from its position.
a Periodic Table organises the different elements, according to the atoms' mass, type, properties, reactivity etc. See the question about: periodic table patterns
Russian chemist Dmitry Mendeleyev constructed the original periodic table about 1870. He arranged his table by grouping the similarities of the various elements.
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
