Question

an
The electronic configuration of
element is ls2,2s²2p 3s 3p". The
atomic number of element present just
below the above element in periodic table
is:​

Answer 1

Answer:

The element which present just below this element will have outermost electronic configuration as 4s24p3, so its full electronic configuration is 1s2,2s22p6,3s23p6,4s2, 3d10,4p3 and hence, its atomic number is 33.

Answer 2

Answer:

The answer is germanium(z=32)

Explanation:

The given element is silicon with 14 electrons i.e it is in the 3rd period. And the element just below it will have the atomic no. 18 more than that of silicon. So the atomic no. of the element just below silicon( germanium) is 14+18=32.

Thank you.
