How were elements arranged on the early Periodic Table of Elements?
before it there was no organization, but the first periodic table was organized by atomic mass.
Hydrogen is before helium on the periodic table because the periodic table arranges elements by increasing .?
atomic number
What has a 5.09 on the periodic table?
Platinum has a relative atomic weight of 195.09(you will not find 5.09 anywhere else on a periodic table.)
Why is the periodic table arranged in order atomic weight?
The periodic table is arranged in order of atomic number, not atomic weight. This is because the properties of elements are determined by the number of protons in the nucleus, which is the atomic number. Atomic weight is not used because it can vary due to isotopes of an element.
What does the atomic number and atomic mass have to do with the arrangement of the elements on the periodic table?
The elements on the periodic table are arranged in order of increasing atomic number.
Who organized the periodic table by atomic number?
Arranging the Periodic Table by atomic number rather than Atomic Mass was first suggested by a British man named Henry Moseley in 1913. Before that point, the periodic table was organized by atomic mass, and has several inconsistencies and problems.
Who used atomic mass to arrange the periodic table?
Mendeleev used atomic mass to arrange periodic table.He gave his model in 1869.

How does atomic number explain the arrangement of the periodic table?
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
What is the atomic number of permanganate on the periodic table?
The atomic number of permanganate on the periodic table is 25.
What is the atomic number of scandium on the periodic table?
The atomic number of scandium on the periodic table is 21.
What is the atomic number of uranium on the periodic table?

How does mendeleevs periodic table differ from moselys periodic table?
Mendeleev's Periodic Table was different from Moseley's in that Mendeleev arranged the elements inÊthe table according to atomic masses while Mosley's periodic table was arranged accordingÊto atomic numbers that were increasing.ÊÊThe modern periodic table used today is based on the Moseley model.
Why is the periodic table arranged in order atomic weight?
The periodic table is arranged in order of atomic number, not atomic weight. This is because the properties of elements are determined by the number of protons in the nucleus, which is the atomic number. Atomic weight is not used because it can vary due to isotopes of an element.
