Question

The members of the oxygen family are located in the p-block.Explain.

Answer 1

electronic cnfiguration of oxygen family,
Oxygen- 1s^2 2s^2 2p^4

Sulfur- 1s^2 2s^2p^6 3s^2p^4

Selenium- 1s^2 2s^2p^6 3s^2p^6d^10 4s^2p^4

Tellurium- 1s^2 2s^2p^6 3s^2p^6d^10 4s^2p^6d^10 5s^2p^4

Polonium- 1s^2 2s^2p^6 3s^2p^6d^10 4s^2p^6d^10f^14 5s^2p^6d^10 6s^2p^4

Livermorium/Ununhexium- 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4f^14 5d^10 6p^6 7s^2 5f^14 6d^10 7p^4 (predicted)
the last electron of the elements inthis group enters in p subshell.hence they are placed in p block
