Question

Which of the two will be chemically more reactive; element X with atomic number 16 or element

Y with atomic number 17? (
​

Answer 1

Answer:

Y ELEMENT (I.e. CHLORINE)

IT'S ATOMIC NO. IS 17

IT'S ELECTRONIC CONFIGURATION IS (2, 8,7)

SO IT'S VALENCY IS 1 ... IT REQUIRES ONLY 1 ELECTRON TO ACHIEVE IT'S.. INERT GAS ELECTRONIC CONFIGURATION..... SO IT'S EASY FOR CHLORINE TO... GAIN 1 ELECTRON.. SO IT IS MORE REACTIVE... AS COMPARED TO SULPHUR... WHOSE ATOMIC NO. IS 16 AND ELECTRONIC CONFIGURATION IS (2, 8,6) IT HAS TO GAIN 2 ELECTRONS TO ACHIEVE INERT GAS ELECTRONIC CONFIGURATION.... SO IT'S SOMEWHAT MORE DIFFICULT THAN CHLORINE....

Answer 2

Answer:

Explanation:

The element with atomic number 17(chlorine)is more reactive cause it needs to gain only one electron to become stable while the element with atomic number  16 needs 2 electrons to become stable.
