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.
Mendeleev arranged the elements in the periodic table according to their atomic masses.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
On the periodic table, the elements are arranged by Atomic Mass. Helium and Hydrgen are at the way top of the table due to how they have the smallest amount of mass. The elements with the biggest mass are at the bottom.

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.
