In a periodical table if goes Left to the right side the electronegativity.
- A.
Decrease
- B.
Remain same
- C.
Increase
- D.
None
Correct Answer
C. IncreaseExplanation
As you move from left to right across the periodic table, the electronegativity of elements generally increases. Electronegativity is the measure of an atom's ability to attract electrons towards itself in a chemical bond. In general, elements on the left side of the periodic table have lower electronegativity because they have fewer protons in their nucleus and their electrons are further away from the nucleus. As you move towards the right side, the number of protons and the positive charge in the nucleus increases, resulting in a stronger pull on electrons and higher electronegativity. Therefore, the correct answer is "Increase".Rate this question:
