(a)
Interpretation:
The electronic configuration of given atom is to be stated and the valence electrons and valence orbitals is to be identified.
Concept introduction:
According to the Aufbau principle, the electrons are firstly filled into the orbitals having lower energy.
According to the Pauli’s principle, no two electrons can have same set of four quantum numbers.
According to the Hund’s principle, the orbitals are firstly singly occupied by electrons and then pairing of the orbitalsstart.

- Which of the following statements about sulfur is FALSE? Group of answer choices H2S is the product of an oxygen-depleted ecosystem. In the acid mine drainage reaction, FeS2 is a product. One allotrope of sulfur has the formula S20. In the environment, bacterial oxidation can convert S2− to elemental S or SO42−.arrow_forwardOf the following choices, which is the best reason that most materials DON'T spontaneously combust even though our atmosphere is about 21% oxygen? Group of answer choices The reduction of O2 in the gas phase (O2 + e− → O2−) is spontaneous. The reduction of O2 in acid solution (O2 + H+ + e− → HO2(aq)) is spontaneous. O2 is not a reactant in combustion. The O2 bond dissociation energy is 494 kJ/mol, leading to a high activation energy for combustion.arrow_forwardplease answer in the scope of the SCH4U course, I am having a hard time understanding, may you show all steps please and thank you! can you also put the final answers in the table so its understandablearrow_forward
