N-પરમાણુના સાત ઇલેક્ટ્રૉનને 1s⁷ વડે દર્શાવવામાં આવે, તો તેની ઊર્જા 1s² 2s² 2p³ ની તુલનામાં નીચી રહે છે. છતાં 1s⁷ સ્વીકાર્ય બને, તો નીચેનામાંથી કયા નિયમનું ખંડન થાય છે ?

હૂંડનો નિયમ
પૌલીનો સિદ્વાંત
હાઇઝનબર્ગનો સિદ્વાંત
આઉફબાઉનો સિદ્વાંત

રસ્તા પર દોડતી કાર, આકાશમાં ઊડતી સમડી હવામાં પગરાજ અને જમીન પર દોડતો ઉંદર ની ગતિ સાથે સંકળાયેલ તરંગલંબાઇનો ક્રમ જણાવો.

P > R > K > M
M > K > R > P
M = K = R = P
P = K > M = R
