Oxygen atom has the greatest attraction for the electrons in a chemical bond. Therefore, option B is the correct answer.
Electronegativity is the tendency of an atom to attract a bonding pair of electrons. Electronegativity increases from left to right in period and decreases from top to bottom in a group.
Fluorine is the most electronegative atom with electronegativity 3.98.
The electronegativity of atoms is given below,
- oxygen = 3.44
- Sulphur = 2.58
- Silicon = 1.90
Hydrogen = 2.2
Therefore, order of attraction for electrons in chemical bond as follows,
Oxygen> Sulphur>Hydrogen>Silicon
Thus, we can conclude that, oxygen atom has the greatest attraction for the electrons in a chemical bond. Therefore option B is the correct answer.
