given that the electronic configuration of an element X is 1s2 2s2 2p6 3s2 3p4,it can be deduced that X:
a. belongs to group VI in the periodic table
b. belongs to period 4 in the periodic table
c. contains 3 unpaired electrons in the ground state
d. has atomic number 27​

Respuesta :

Answer:

Option A

Explanation:

The element X belongs to

=> Period 3 (Because it's valence shell is 3)

=> Group VI (Because electrons in the valence shell , 2+4 = 6)

The element X can be deduced to:

a. belongs to group VI in the periodic table

Periodic table:

It is the arrangement of elements in the order of increasing atomic number.

Given Electronic configuration of element X:[tex]1s^2 2s^2 2p^6 3s^2 3p^4[/tex].This element has an atomic number 16. The element having atomic number 16 is Sulphur. It belongs to: Period 3 (Because it's valence shell is 3)Group VI (Because electrons in the valence shell , 2+4 = 6)Thus, Element X  belongs to group VI.

Therefore, correct option is a.
