Passage / Comprehension

In general electronegativity increases from left to right in a period and decreases from top to bottom in a group. Pauling scale is the most widely used scale for electronegativity

Two elements of x and y of 3 rd period forms oxides $X_{2} O$ and $XO_{3}, X_{2} O$ is basic whereas $YO_{3}$ is acidic in nature. If the electronegativity of these two elementsw are 0.9 and 2.5 (not in order)

Answer:

2.50

Solution:

$X_{2} O YO_{3} \Rightarrow$ EN and $X < Y$

(Basic) (Acidic) 0.9 2.50
