The elements with same properties need to be grouped together. So that it is easier to study the elements
we use a periodic table to learn the elements
he developed the first periodic table in the increasing order of atomic masses of elements.but after the discovery of isotopesthis periodic table was not consider to be effective.
A Russian chemist and the periodic table of elements
Mendeleev was a Russian chemist who organized the periodic table.
A Periodic table The Periodic Table of the Elements.
atomic number
so that it will be acceptable in modern lives of the people in the world
the bottom of the Periodic Table. why? a metal looses electrons and at the bottom of the periodic table is the lowest amount of ionization energy (the energy needed to remove electrons) with low ionization energy, not much energy is needed to remove those electrons making it faster and easier to do so.
1s22s22p6.
Mendeleev arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
A normal periodic table does not list isotopes, but elements, almost all of which occur in more than one isotope, and there is probably at least one radioactive isotope for every element. Instead of the periodic table, a table of nuclides is needed to answer this question.
No, brass is an alloy of the elements copper and zinc that have various proportions in the different mixtures needed in industry.
