The electronegativity from least to highest : Cadmium, Aluminum (aluminium), and Oxygen.
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.)

Mendeleev arranged the elements in the periodic table according to their atomic masses.
N (smallest radius) P As Sb (largest radius)
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
N, P, As and Sb
Dmitri Mendeleev decided to arrange his cards by organizing elements with similar properties into groups and leaving gaps for undiscovered elements. He then ordered the groups by increasing atomic weight, which led him to identify patterns and create the periodic table of elements.

The elements are arranged in order of increasing atomic number. Also elements in the same column have simmilar properties.
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 atomic mass and repeating properties so that it is easy to study the properties / reactivities of the elements.
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
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.

The inversion is due to the isotopic composition of these elements.
