Can anelementwith atomicnumber126, if discoveredbe accommodate in thepresentset up ofthe longform of theperiodictabel ?

Answer»

SOLUTION :No. themaximumnumberof elementswhichcan beaccommodated in the presentset upof thelong formof the priodictable is`118. thereforefillingof 8s-orbital shallbeginwhichwillaccommodate only twoelectrons . After 8s-orbitals , the filingof 5g- orbitals will begin.
