As you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. Electronegativity increases as you move from left to right across a period on the periodic table. Considering the above facts we get the order:S<Cl <O <F

The concept of electronegativity refers to this type of chemical bond. As the participating atom becomes more electronegative, the bonding (shared) valence electrons will be pulled increasingly closer to its nucleus (unequal sharing between the bonded atoms).

Electronegativity (E.N) of elements are; F = 4,Cl =3,N = 3,O = 3.5. Therefore, the trend is : F>O>N =Cl. This can be explained as, on moving from left to right across a period, the E.N increases and also on moving down a group from top to bottom the E.N decreases.

In a period, electronegativity increases from left to right. In a group, electronegativity decreases from top to bottom.

The correct option is A F > CI > Br > I It decreases on moving down the group because size of atom increases. Decreasing order of electro-negativity of halogens is F, Cl, Br, I. Fluorine has highest electronegativity among all the known elements.

Electronegativity: Electronegativity refers to how strongly an atom attracts a pair of bonding electrons in a covalent bond. The more strongly it attracts the electrons, the more electronegative it is. Electronegativity increases when an atom has more protons and fewer energy levels. Differences in electronegativity between bonded atoms can be used to determine the polarity …

Electronegativity: The electronegativity word refers to the element's property which deals with the "electron affinity." The "atomic number and size" have significance in predicting electronegativity. The ionization energy is concerned with this property.

Electronegativity: Most elements in the periodic table have a known electronegativity value in the literature. This refers to how the element's atom acts when participating in a covalent bond. In general, as the electronegativity increases, the participating atom will pull the bonding valence electrons more towards its own nucleus.

Example of Electronegativity As compared to the hydrogen atom the chlorine atom has is highly electronegative, therefore, the electrons which form a bond will be nearer to the Cl than to the H in HCl molecule. The electrons which are present in the covalent bond equally share the two atoms of oxygen. Solved Question for You Ques.
