What tells you how heavy an elements atoms are compared with atoms of other elements?
the atomic weights on the periodic table
Why is the periodic table arranged in order atomic weight?
The present periodic table is arranged in order of increasing atomic numbers not the atomic weights , before modern periodic law the elements were arranged on the basis of atomic weights.
The elements in the periodic table goes accoring to?
In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
Can you find any cases in the first 90 elements in which consecutive elements do not have increasing atomic weights?
Yes: argon to potassium.
What is mendeleev's quotation?
The elements if arranged according to their atomic weights, exhibit an periodicity of properties
Base weight a system of comparing atomic weights to carbon is it true or false?
True. The unit for the atomic weights of chemical elements is the relative atomic mass unit (1/12 from the atomic mass of the isotope 12C). Note that atomic weights is used for elements and atomic mass for isotopes.
What are the four elements smaller than uranium?
All the elements with the atomic number under 92 has atomic weights smaller than uranium.
What is the sum of atomic mass?
I suppose that you think to atomic weights (not mass) of chemical elements and the molecular mass.
How are chemicals related to atomic mass?
The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.The expression atomic weight is correct for elements; for isotopes is correct atomic mass.
What tells you how heavy an elements atoms are compared with atoms of other elements?
the atomic weights on the periodic table
What tells you how heavy elements atoms are compared with atoms of other elements?
the atomic weights on the Periodic Table
The atomic weights of the elements contain fractional amounts because?
all of the above
Arranged the elements in the periodic table according to increase in atomic weights?
Mendeleev.
How did Mendeleyev organize the periodic table of elements?
In increasing order of atomic weights.
Why is the periodic table arranged in order atomic weight?
The present periodic table is arranged in order of increasing atomic numbers not the atomic weights , before modern periodic law the elements were arranged on the basis of atomic weights.
What is the molar mass of all ther elements?
The molar mass of any element is its atomic weight in grams. The atomic weights of the elements are found on the periodic table.
Why it is necessary to introduce amu unit?
The atomic mass unit is necessary to evaluate the atomic weights of chemical elements (or atomic masses of isotopes).
