Question

The electronic configration of 'x' is 2,8,6.
To which group and period of the modern
Periodic table does 'x' belong .state it
Valency and justify your answer in each case

Answer 1

I have written it by myself please mark it as the brainllist if it will help you please say thanks for this answer too.

Answer 2

the element x is sulphur because

its electronic configuration is 2,8,6 and thus atomic number = 2+8+6=16

sulphur is the element of atomic number 16

 

since it has three shells 2,8,6 it belongs to the THIRD PERIOD of the modern periodic table

it requires 2 more electrons to satisfy the octet rule and attain noble gas configuration.  therefore its valency is 2

VALENCY IS 2
