Why is it better to arrange elements according to their electronic structure and not in order of their relative mass number?

The chemical properties of any given element are the result of it electronic structure. The mass number is not related to the electronic structure because the mass includes neutrons, which not related to the electron structure (unlike protons). Any given element exists in more than one form (called isotopes) which have different numbers of neutrons, but the same electronic structure (and the same number of protons).

Why are some atoms are heavier than others?
some atoms are heavier than others as they have higher relative Atomic Mass, by which is equals to proton number + number of neutrons in an atom, according to the Periodic Table of the elements
The chemical formula of a compound does not indicate?
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
What does re activity series show?
It's a somewhat crude indication of the elements' relative 'willingness' to form chemical bonds with other elements.
What trend do you see in the relative electronegativity values of elements within a group?
It decreases from top to bottom!
What are the differences between galvanic series and emf series?
1)galvanic series is for both elements and alloys whereas emf series is only for elements 2)galvanic series tells about relative tendencies of corrosion whereas emf series tells about relative tendencies of displacement
Why is the noble gases a group of un-relative elements?
because they have completely filled electronic configuration.
Why is it better to arrange elements in terms of their electronic structure and not in order of their relative atomic masses?
It's not better to do that for everyone, but it certainly is for chemists, since the electron structure of atoms is the building blocks for pretty much...everything they study. Nuclear physicists would surely rather arrange the elements based on atomic masses, for...something I'm sure. Fortunately, the Periodic Table of the Elements has them arranged both ways at the same time, whew!
What is age structure?
According to the textbook Biology by Campbell and Reece, published in 2002, age structure is defined as the relative number of individuals of each age in a population.
What relative unit of measure is used in CSS to let elements scale according to the browser's text size?

Why Nb3Sn have A15 structure?
Look at the diagram at the top of page 644. (I would have included a link to just the image, but that is impossible for me to do) An A15 typer structure is based on the relative percentages of the elements in the molecule. Nb3Sn has a 3 Nb to 1 Sn ratio which gives it a specific bond structure which is classified as A15.
Why are some atoms are heavier than others?
some atoms are heavier than others as they have higher relative Atomic Mass, by which is equals to proton number + number of neutrons in an atom, according to the Periodic Table of the elements
What is the relative concentration of elements on lunar surface compared to earth's surface?
The relative concentration of elements on lunar surface compared to earth's surface is known as regolith.
What is the best humidity level for electronic equipment?
40% to 60% relative humidty
