Why is it possible to separate substances in a mixture?
Because of the charges of particles and different atomic weights of both elements and compounds.
True or false a Russian chemist Dmitri mendeleyev constructed the periodic table by which he calculated the atomic weights of the different elements?
True--PainRain
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.
Did John Dalton stat that different atoms have different weights?
its not true The answer to the Question in (no)
Who constructed the periodic table by which he calculated the atomic weights of the different elements?
Dmitri Mendeleyev
Do all elements have the same atomic weight?
No they are all different and even some atoms of the same element have different weights
What is radioactivity number?
There is no such thing. There are elements with isotopes that have different atomic weights and these decay [radioactively] into daughter elements which will also have a range of atomic weights. There is also the half-life, which is a measure of the time before half the atoms in a lump of a substance have decayed.
Why is it possible to separate substances in a mixture?
Because of the charges of particles and different atomic weights of both elements and compounds.
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 is the mass of 4000 molecules of nitrogen?
Nitrogen is an element(atom), not a molecule. atomic weights are not a constant of nature and depend on the physical and chemical history of the elements. isotopes have different weights.
How the elements of isotopes are alike and how they are different?
Elements can exist in the form of different isotopes. Isotopes of the same element have the same number of protons in their nuclei but have different numbers of neutrons. The first gives them the same atomic number and chemical properties while the second gives them different atomic weights.
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.
True or false a Russian chemist Dmitri mendeleyev constructed the periodic table by which he calculated the atomic weights of the different elements?
True--PainRain
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 elements atoms are compared with atoms of other elements?
the atomic weights on the Periodic Table
