1.	Hydrogen is the 1st element. The elements in the periodic table are arranged with respect to their __________(a) atomic numbers(b) molecular weights(c) atmospheric abundance(d) physical stateI had been asked this question during an interview.I want to ask this question from Position of Hydrogen in the Periodic Table in section Hydrogen of Chemistry – Class 11
Answer» CORRECT option is (a) ATOMIC numbers The best explanation: We all KNOW that the elements in the periodic table are arranged according to their atomic numbers and atomic numbers are NOTHING but the number of PROTONS in that element. So hydrogen takes the first place.
