Question

Which of the two world be More rective element x of atomic number 18 or element Z of atomic number 16 and why

Answer 1

Answer:

Hi friend

Here is your answer..

Explanation:

Z will be more reactive .

As, x has 18 as atomic number, it's electronic configuration will be (2,8,8)

Hence, it becomes a noble gas .

Noble gases are very inert and unreactive in nature .

Answer 2

Answer:atomic no. 16 more reactive

Explanation:atomic no. 18 belong to noble gases they have completely filled outer electronic configuration , fully filled e.c so they are stable

But in a.no. 16 belong to oxygen or chalcogen family that incomplete p orbital electronic configuration , so they are reactive
