Question

Three element of 3° period x, y, z such that the oxide of x is acidic, y is amphoteric and z is basic, the order of atomic no. of three elements is :

(1)x>y>z
(2)y>x>z
(3)z>x>y
(4)x>z>y

Answer 1

Answer:

Option 1

This is the answer.

Hope this helps you.

Explanation:

Because acids are stronger than amphoteric and amphoteric is stronger than basic.

Answer 2

GIVEN:-

● Three element of 3° period x, y, z such that the oxide of x is acidic, y is amphoteric and z is basic.

TO FIND:-

● The order of atomic no. of three elements .

EXPLANATION :-

We know ,

Non metal $\rightarrow$ Acidic

And ,

Metals $\rightarrow$ Basic.

Also , Acidic > Amphoteric >basic.

》 Given that oxide of x is acidic, y is amphoteric and z is basic,

In third period ,

》 MgO is metal ; Al2O3 is amphoteric & SO2 is Nonmetal.

Hence , x > y > z
