number of protons
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
Compared to Mendeleev's periodic table which was arranged my atomic mass, Moseley's was, however, arranged by atomic number.
It's Is Arranged By Matals, NonMetals,Matalliods And Moble Gases
Demitri Mendeleev. He arranged it by atomic mass
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.
Atomic number
Yes!The elements are arranged in horizontal rows and vertical columns to represent what is called the periods on the periodic table.
The modern version of the periodic table is arranged according to the atomic number.
Periodic table is arranged by atomic number. elements are arranged in groups and periods.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
The Periodic Table is arranged like it is for a specific reason. It is probably called the Periodic Table because it is made up of "periods" or horizontal rows.
The Modern Periodic Law states that there will be a periodic repetition of properties when the elements are arranged according to increasing atomic number.
The periodic table.
Dmitri Mendeleev is credited with arranging the elements in the periodic table according to increasing weight. He also left gaps for undiscovered elements and predicted their properties, leading to the development of the modern periodic table.
Mendeleev arranged the periodic table according to The Natural History Museum, Google, Experienced scientists and of course himself. This suggests he did arrange the periodic table.
According to the number of their protons
The elements arranged according to their atomic number in the table are called periodic table.
