Which is the electronic configuration of the outermost shell of group 16 elements?

1) Electronic Configuration : All these elements of this group have `s^(2)p^(3)` configuration in their respective outmost orbits. Nitrogen (N) : [He] `2s^(2)2p^(3)`, phosphorus (P) : [Ne] `3s^(2)3p^(3)`, Arsenic (As)...

Correct Answer - D `5s^(2),5p^(4)` configuration is actually` ,""_(36)[Kr]5s^(2),4d^(10),5p^(4)` i.e., 5th period and group 16 and the element is tellurium .

Correct Answer - A Five vacant orbitals (3d-level) are present in Cl `(1s^2 2s^2 2p^6 3s^2 3p^5)` which belongs to 3rd period.

Correct Answer - D Valence shell i.e. outer electronic configuration of inert gases except He i.e. `ns^2 np^6` . He is `1s^2`

Correct Answer - B `3d^5` have five unpaired `e^-` in 3d orbitals (which is maximum )

Correct Answer - B We know that, in 4f series outer most subshell is s which contains 2 electrons.

Correct Answer - C Since the common oxidation state of metal is -2. This indictaes it is 2 electrons short of noble gas configuration. Therefore, it has six electrons in valence...

Correct Answer - B Halogens have seven electrons in their valence shell so these have valence shell electronic configuration of `ns^2 np^5`

Correct Answer - C Valency of A is 3 and that of X is (8-6), i.e.2

Correct Answer - C Configuration of `Cl^-` ion is `1s^2 2s^2 2p^6 3s^2 3p`
