What is used to determine the order in which the elements are placed on the periodic table?
All elements are surrounded by electrons. The electrons fit into orbits. The first orbit holds two electrons. All the rest hold more. Each orbit is one level in the chart. When an orbit is full, then the chart starts again at the next level. As a result the first element in each level has one electron in its outer orbit. The chart gives an understanding of the properties of the elements above and below a particular element as well as alongside a particular element. Platinum worked in a catalytic converter. It was expensive. Someone tried other elements in the Platinum group. They also worked and cost less.
If you are referring to their arrangement on the Periodic Table, then the is atomic number. The atomic number is the same as the number of protons, so the elements are arranged by increasing number of protons.
What else can I help you with?
What was Dmitri medeleevs contribution to the periodic tale?
Mendeleev arranged the elements in order of increasing atomic mass.He placed the elements in rows and columns.
How are element placed in periodic table based on electronic configuration?
Elements are placed in the periodic table based on their electronic configuration, which refers to the arrangement of electrons in the atom's energy levels or orbitals. Elements with similar electronic configurations are placed in the same column or group of the periodic table. The periodic table organizes elements in order of increasing atomic number and arranges them into rows and columns based on their electronic structure.
Which two elements on a periodic table be reversed if you used atomic mass?
Tellurium (Te) and iodine (I) would be in reverse order if the elements were placed in order of atomic mass instead of atomic number.
What are the order of elements on the periodic table based on?
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
What are some ways that elements are arranged on the periodic table of elements?
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
Elements in a periodic table in common?
The periodic table contain all chemical elements, placed in a rational order.
What did Dimitri Mendeleev discovered?
He discovered the elements and and weighed them and latter placed the elements in order to form the periodic table.
Why is hydrogen placed first in the periodic table?
Because It has 1 proton. The elements on the periodic table are order by the number of protons.
How is each elements placed on the periodic table?
Each element is placed according to the increasing order of their atomic number and repeating properties.
What was Dmitri medeleevs contribution to the periodic tale?
Mendeleev arranged the elements in order of increasing atomic mass.He placed the elements in rows and columns.

What Demetri Mendeleev doe for the periodic table?
Dmitri Mendeleev arranged elements in order of increasing atomic masses. He placed elements in rows and columns.
What property is used to determine the order of the elements on the modern periodic table?
The atomic number is used to determine the order of the elements on the modern periodic table. The atomic number represents the number of protons in the nucleus of an atom, which defines the element. Elements are arranged on the periodic table in order of increasing atomic number.
Mendeleev's periodic table is arranged how?
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.
Which two elements on a periodic table be reversed if you used atomic mass?
Tellurium (Te) and iodine (I) would be in reverse order if the elements were placed in order of atomic mass instead of atomic number.
Elements were originally placed in order of atomic now they are placed in order of atomic?
Elements were originally placed in order of atomic massnow they are placed in order of atomic number
When Mendeleev developed his periodic table he placed the greatest emphasis on?
When Mendeleev developed his periodic table, he placed the greatest emphasis on organizing the elements based on their atomic masses and grouping elements with similar properties together. He also left gaps for undiscovered elements and predicted their properties.
