the man who first arranged the elements according to atomic mass and noticed q periodic recurrence of their physical and chemical properties was Dmitri Mendeleev.
that many of the physical and chemical properties of the elements tend to recur in a systematic manner with increasing atomic number.
Periodic Table of elements.
The Periodic Law states these facts about properties of elements. The Russian chemist named Dmitri Mendeleev was the first to state this law in 1869.

Since oxygen is an inorganic substance, most likely an inorganic chemist would describe the chemical properties of oxygen.
it is physical because when the metal melts it is still metal. it doesn't change to a new subtance.--------------------------------------A metal is a chemical element, not a property; but in some situations chemist use the expression metallic characteristics (or properties).
A chemist tries to examine the properties and composition of matter. A chemical engineer tries to create or manufacture matter.
This was the Russian chemist Dmitri Mendeleev in 1869.
A Russian chemist named Dmitri Mendeleev wrote it and this periodic table was a table to illustrate recurring trends in the properties of elements.
The arrangement of chemical elements into the widely recognised periodic table was first devised by the Russian chemist Dimitri Mendeleev.
The periodic table of the chemical elements (also periodic table of the elements or just the periodic table) is a tabular display of the chemical elements.Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements.The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.
