Compared to Mendeleev's Periodic Table which was arranged my Atomic Mass, Moseley's was, however, arranged by atomic number.
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
Mendeleev arranged his version of the Periodic Table in terms of ascending atomic weights and similar properties. Since it was first published in 1869, there have been updates and improvements.
He is important because he was the person who invented the Periodic Table and made it how it is today
number of protons
He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.
Yes depending on which scientists version of the periodic table you look at. Henry Moseleys ideas on the periodic table was the first to increase by atomic number.

The Periodic Table was arranged by atomic number.
The elements arranged according to their atomic number in the table are called periodic table.
The periodic table is arranged from left to right in the order of atomic numbers.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
Periodic table is arranged by atomic number. elements are arranged in groups and periods.
The periodic table is arranged by the Atomic Number
All of the known 118 naturally occurring and synthetic elements are arranged on the periodic table.
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
