Each element has its own Atomic Mass.
What else can I help you with?
Define periodic law?
Properties of elements are a periodic function of their atomic masses.
How were the elements arranged in the spiral periodic table?
in order of their reletive atomic masses
State the periodic law on which Mendeleev's Periodic table was based and why and how this periodic law changed?
Mendeleev's Periodic Table was based on the periodic law which states that the properties of elements are a periodic function of their atomic masses. This law changed with the discovery of atomic number by Moseley which stated that the properties of elements are a periodic function of their atomic numbers, leading to a more accurate and modern periodic table based on atomic number.
How did Mendeleev arrange chemical elements?
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
How were the atomic number and the atomic masses of the elements determined?
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
How did mandeleev arranged chemical elements?
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
What method did Dmitri use to organize the elements of the periodic table?
Dmitiri Mendeleev arranged the Periodic Table of elements in order of increasing atomic masses.
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.
Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
Who was or is Mendeleev in periodic tables?
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
Who discover the old Periodic Table?
Mendeleev discovered old periodic table. He arranged elements in order of atomic masses.
How Mendeleev organized his periodic table?
By the increasing Atomic Mass.
