Who was the Russian chemist show a definite relationship between chemical properties and atomic weights of the elements?
Mendeleev
What is the relationship between the atomic numbers and ionic radii of the elements in the group 3A?
I think that the ionic radii decrease
Is there any relationship between atomic mass and number of proteins and electrons?
the atomic number is equal to the number of electrons(-) and protons(+): that is why elements have no charge, as a neutron is neural
What you the relationship between the number of protons and the atomic number of an atom?
The number of protons is the atomic number.
What is the relationship between a atomic number and an atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
What is the relationship between the atomic number and the elements identity?
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
What is the relationship between the atomic mass of an element and a mole of that elements atoms?
The mole is the atomic weight expressed in grams.

What is the law of traid?
A German chemist Dobernier observed relationship between atomic masses of several groups of three elements called traids.In these groups the central or middle element had atomic mass average to the other two elements.
What is the relationship between an atoms atomic number and one mole of that atom?
There is no general exact relationship, because of the existence of neutrons in the nuclei of almost all elements and the lack of effect of neutrons on atomic number. An atom's gram atomic mass, however, is equal to the mass of one mole of the atoms in question.
Is there a difference between mass and atomic mass when dealing with elements?
Generally the term "atomic mass" is used for isotopes. For elements is preferred now "atomic weight".
What is the Name of scientist who sorted the elements into order?
In 1913, almost fifty years after Mendeleev, Henry Moseley published the results of his measurements of the wavelengths of the X-ray spectral lines of a number of elements which showed that the ordering of the wavelengths of the X-ray emissions of the elements coincided with the ordering of the elements by atomic number. With the discovery of isotopes of the elements, it became apparent that atomic weight was not the significant player in the periodic law as Mendeleev, Meyers and others had proposed, but rather, the properties of the elements varied periodically with atomic number. When atoms were arranged according to increasing atomic number, the few problems with Mendeleev's periodic table had disappeared. Because of Moseley's work, the modern periodic table is based on the atomic numbers of the elements.
What are the elements with atomic numbers from 58 to 71 called?
The elements with atomic numbers between 57 and 71 are called lanthanoids (or lanthanides).
How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
What is the relationship between melting point and atomic number for group seven elements?
As the atomic number increases so does the melting point, meaning the the molecules get stronger therefor you need a higher melting point to break the molecules.
