Question

taking the example of an element with atomic number 16, explain how the electronic configuration of the atom of an element relates to its position in the modern periodic table and how valency of an element is calculated on the basis of its atomic number.

Answer 1

HEY MATE!

HERE IS YOUR ANSWER:

ATOMIC NUMBER: 16

ELECTRONIC CONFIGURATION:2,8,6

VALENCY:2 {8-6=2}

• SINCE THE ELECTRONIC CONFIGURATION CONSIST OF 3 DIGITS , WE CAN KNOW THAT THE ELEMENT IS IN THE THIRD PERIOD AND SINCE THE VALENCY IS 2 AND THE VALENCE SHELL HAS 6 ELECTRONS, WE CAN KNOW THAT THE ELEMENT IS IN THE 16TH GROUP.
