the elements are arranged by atomic weight, mass, and the amount of electrons. if you look at the Periodic Table it sort of counts lowest to highest when it comes to Atomic Mass, weight, and the amount of electrons except for the bottom squares that are separated for reasons i do not know.
The most important, between other chemists, was Dimitri Mendeleev.
Dmitri Mendeleev
Moseley arranged elements according to atomic number.Mendeleev arranged elements according to atomic mass.
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
elements in the same group
The chemical and physical properties of a compound are different than those of the elements from which it is formed.
These elements have similar chemical and physical properties.
