Electronegativity propto non-metallic character propto ( text1/ textmetallic textcharacter) ∵ The element (X) form acidic oxide, so it is a non-metal, while the element (Y) form basic oxide, so (V) is a metal. Thus, the order of their electronesativity is X>Z>Y

Q. The elements X,Y and Z form oxides which are acidic, basic and amphoteric respectively. The correct order of their electronegativity is

$X > Y > Z$

$Z > V > X$

$X > Z > Y$

$Y > X > Z$

Electronegativity $\propto$ non-metallic character $\propto \frac{1}{metallic character}$ $∵$ The element (X) form acidic oxide, so it is a non-metal, while the element (Y) form basic oxide, so (V) is a metal. Thus, the order of their electronesativity is $X > Z > Y$

Q. The elements X,Y and Z form oxides which are acidic, basic and amphoteric respectively. The correct order of their electronegativity is

X>Y>Z

Z>V>X

X>Z>Y

Y>X>Z

Electronegativity ∝ non-metallic character ∝metalliccharacter1​ ∵ The element (X) form acidic oxide, so it is a non-metal, while the element (Y) form basic oxide, so (V) is a metal. Thus, the order of their electronesativity is X>Z>Y

$X > Y > Z$

$Z > V > X$

$X > Z > Y$

$Y > X > Z$

Electronegativity $\propto$ non-metallic character $\propto \frac{1}{metallic character}$ $∵$ The element (X) form acidic oxide, so it is a non-metal, while the element (Y) form basic oxide, so (V) is a metal. Thus, the order of their electronesativity is $X > Z > Y$
