1.	Give the name and atomic number of the inert gas atom in which the total number of d-electrons is equal to the difference between the numbers of total p and total s electrons.
Answer» Electronic configuration of Kr (atomic no.=36) = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ Total no. of s-electrons = 8, total no. of p-electrons = 18. Difference = 10 No. of d- electrons = 10

Give the name and atomic number of the inert gas atom in which the total number of d-electrons is equal to the difference between the numbers of total p and total s electrons.

Answer»

Electronic configuration of Kr (atomic no.=36) = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶

Total no. of s-electrons = 8, total no. of p-electrons = 18.

Difference = 10

No. of d- electrons = 10
