I used the web to answer so I'm not sure if this is right
Aufbau principle:
Electrons are added one at a time from the lowest energy orbitals available until all the orbitals are filled.
According to the Aufbau principle, electrons fill lower energy orbitals first.
(i) Boron (Z = 5)
Electronic configuration =
(ii) Neon (Z = 10)
Electronic configuration =
(iii) Aluminium (Z = 13)
Electronic configuration =
(iv) Chlorine (Z = 17)
Electronic configuration =
(v) Calcium (Z = 20)
Electronic configuration =

Answer:
Classification of elements in groups provide us with a fixed pattern in which the elements change their properties periodically.
Explanation:
Answer:
The main use for hydrogen sulfide is in the production of sulfuric acid and elemental sulfur. ... H2S is used to prepare the inorganic sulfides you need to make those products. As a reagent and intermediate, hydrogen sulfide is beneficial because it can prepare other types of reduced sulfur compounds.
