if its for apex learning then the answer is bromine
Al, Ca, H, or K?
H
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.)

Nitrogen has the greatest Pauling electronegativity: 3,04.
Fluorine has the greatest electronegativity.
The highest value of electronegativity is for fluorine: 3,98 (after Pauling).
Fluorine is the most electronegative element. The Pauling electronegativity value for fluorine is 3.98.

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.
He arranged elements in order of increasing atomic masses. He left gaps for undiscovered elements.The elements with same properties were grouped together.

Oxygen < Water < Sugar. The force of attraction between particles is based on the intermolecular forces present. Oxygen molecules have weak London dispersion forces, water molecules have hydrogen bonding which is stronger, and sugar molecules have intermolecular forces such as hydrogen bonding and dipole-dipole interactions that are stronger than oxygen but weaker than water.

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.

increasing Proton number.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
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.
