The order in the first attempt in the Periodic Table was in the increasing order of atomic weights of atoms. This gave 2 different places for isotopes of the same element with same properties and the same place for isobars with different properties. This was so because chemical properties of an element depends on its number of electrons which is basically given by the atomic number and not atomic weight. Again the lanthanides and actinides had different places inspite of having similar properties due to same atomic number.
The elements arranged according to their atomic number in the table are called periodic table.
The short answer is yes - the periodic table is about order.
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
By Atomic Mass
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
he developed the first periodic table in the increasing order of atomic masses of elements.but after the discovery of isotopesthis periodic table was not consider to be effective.
On the periodic table there is no such order of first and second as asked in the question.
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
Because It has 1 proton. The elements on the periodic table are order by the number of protons.
As the periodic table is arranged in order of increasing atomic number hydrogen is the first element in the periodic table as it has only one electron.
- the periodic table is organized in periods and groups- chemical elements are listed in the order of the atomic number- the periodic table obey the law of periodicity
The elements arranged according to their atomic number in the table are called periodic table.
Mendeleev arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Dmitri Ivanovich Mendeleev
The different elements are arranged in the increasing order of their atomic number and repeating chemical / physical properties.
The short answer is yes - the periodic table is about order.
