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.)

By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.
This periodic pattern is known as the periodic table of elements. It helps scientists predict the properties of elements based on their position on the table and understand trends in properties such as reactivity, electronegativity, and atomic size. The arrangement of elements in the periodic table is based on their electron configurations.
The correct order from smallest to largest ionic radius is chloride ion < sulfide ion < potassium ion < calcium ion.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
The atomic number of an atom is the number of protons in its nucleus, which determines its chemical element. It is always a whole number and is used to arrange elements on the periodic table in increasing order of atomic number.

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.
if its for apex learning then the answer is bromine
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.
