Which of the following statements regarding the blocks and classifications of the modern periodic ta — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Group 18 (Noble gases) have the stable $ns^2 np^6$ configuration (except He). Transuranic elements are those placed after Uranium ($Z=92$) and are artificially synthesized. The 7th period contains $2(s) + 14(f) + 10(d) + 6(p) = 32$ elements. Statement B is incorrect because typical elements belong to the 3rd period, while 2nd period elements act as bridge elements.
