Three elements X, Y and Z are in the 3^rd period of the periodic table.

Question:

Three elements $X, Y$ and $Z$ are in the $3^{\text {rd }}$ period of the 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:

  1. $Z

  2. $\mathrm{X}<\mathrm{Z}<\mathrm{Y}$

  3. $\mathrm{X}<\mathrm{Y}<\mathrm{Z}$

  4. $\mathrm{Y}<\mathrm{X}<\mathrm{Z}$


Correct Option: , 3

Solution:

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)

$\therefore \quad \mathrm{X}<\mathrm{Y}<\mathrm{Z} \quad$ (acidic character)

$X
