- Until the early 1960s the group 8A elements were called the inert gases; before that they were called the rare gases. The term rare gases was dropped after it was discovered that argon accounts for roughly 1% of Earth’s atmosphere. (a) Why was the term inert gases dropped? (b) What discovery triggered this change in name? (c)What name is applied to the group now?arrow_forwardThe oxygen and nitrogen families have some obvious sim-ilarities and differences.(a) State two general physical similarities between Group5A(15) and 6A(16) elements. (b) State two general chemical similarities between Group5A(15) and 6A(16) elements.(c) State two chemical similarities between P and S.(d) State two physical similarities between N and O.(e) State two chemical differences between N and O.arrow_forwardDiscuss each conclusion from a study of redox reactions:(a) The sulfide ion functions only as a reducing agent.(b) The sulfate ion functions only as an oxidizing agent.(c) Sulfur dioxide functions as an oxidizing or a reducing agentarrow_forward
