Question

Acidic Character decreases along a period from left to right? 


  1. True

  2. False


Solution

The correct option is B

False


We know that atomic size increases down the group and the electronegativity decreases down the group and the electropositive nature increases down the group. And Electronegativity increases along a period from left to right and electropositive nature decreases.

In general, the electropositive character of oxide's central atom will determine whether the oxide will be acidic or basic. The more electropositive the central atom, the more basic. The more electropositive the central atom, the more basic the oxide.

Because an electropositive atom can take an electron easily while an electron easily while an electronegative atom will not take an electron easily.

The more electronegative the central atom, the more acidic is the oxide.

Electropositivity increases down the group, so does basic nature

Therefore, we know

electronegativity increases from Left to right along a period and so does acidic character.
