Three elements X, Y and Z are in the `3^(rd)` periodic table. The oxides of X, Y and Z, respectively, are basic, amphoteric and acidic, The correct order of the atomic numbers of X, Y and Z is :

A

`Z lt Y lt X`

B

`X lt Y lt Z`

C

`X lt Z lt Y`

D

`Y lt X lt Z`

Text Solution

Verified by Experts

The correct Answer is:
B
When we are moving from left to right in a periodic table acidic character of oxides increases (as well as atomic number of atom increases)
`therefore X lt Y lt Z` (acidic character)
`X lt Y lt Z` (atomic number)
