The Periodic Table of Elements.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
The periodic table used to be arranged by increasing atomic mass. Now, it is arranged by increasing atomic number (number of protons in an atom of element).
Arrange the following substance in increasing order of forces of attraction between the particles- water, sugar and oxygen.
In Mendeleev's periodic table the elements are arranged in increasing atomic mass and repeating properties whereas in in the modern periodic table the elements are arranged in increasing atomic number and repeating properties.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
The electronegativity from least to highest : Ba, Be, Bi, B, Br The electronegativity of an element is a measurement of how its atoms attract electrons. This is based on the atomic weight (width of the atomic nucleus) and the distance of its valence electrons from the nucleus. As displayed on the Periodic Table, elements generally increase in electronegativity as you move across (left to right), and decrease as you go down the table. (Only aluminum does not follow this in this set of elements.) (see related link)
Mendeleev arranged the elements in the periodic table according to their atomic masses.
The inversion is due to the isotopic composition of these elements.
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
