why is the addition of electron in the outmost shell of sulphur is easier as compared to that of oxygen
Answers
Answer:
Explanation:
Oxygen is the most abundant element on this planet. The earth's crust is 46.6% oxygen by weight, the oceans are 86% oxygen by weight, and the atmosphere is 21% oxygen by volume. The name oxygen comes from the Greek stems oxys, "acid," and gennan, "to form or generate." Thus, oxygen literally means "acid former." This name was introduced by Lavoisier, who noticed that compounds rich in oxygen, such as SO2 and P4O10, dissolve in water to give acids.
The electron configuration of an oxygen atom --[He] 2s2 2p4 --suggests that neutral oxygen atoms can achieve an octet of valence electrons by sharing two pairs of electrons to form an O=O double bond.According to this Lewis structure, all of the electrons in the O2 molecule are paired. The compound should therefore be diamagnetic --it should be repelled by a magnetic field. Experimentally, O2 is found to be paramagnetic --it is attracted to a magnetic field. This can be explained by assuming that there are two unpaired electrons in the * antibonding molecular orbitals of the O2 molecule.
