CBSE Board | Homework Help

There are many question banks and other reference material based for social science. I personally refer the Oswal question bank and Oswal question paper series of all subjects. You can buy them on Amazon. It's really helpful

Electronic configuration of O = 1s2 2s2 2p4 and that for N = 1s2 2s2 2p5. Here, in N, the 2p subshell already has a HALF FILLED electronic arrangement unlike in O. This ensures greater stability for N atom than for O atom and thus, ionisation enthalpy (energy required to remove outermost electron) for O becomes lesser in magnitude than that for N.

Be has an Electronic configuration of 1s2 2s2 and B has an electronic configuration of 1s2 2s2 2p1. The p 2p orbital, causing lesser shielding effect than 2s orbital, would be able to loose an electron much more easily than 2s orbital. Hence, Be has greater ionization enthalpy than B.

दीनार नामक सिक्के का प्रचार किसी समय एशिया और यूरोप के बहुत से भागों में था। यह कहीं सोने का, कहीं चाँदी का होता था। ... अरबी फालकी के कोशकारों ने दीनार शब्द को अरबी लिखा है, पर फारस में दीनार का प्रचार बहुत प्राचीन काल में था। इसके अतिरिक्त रोमन (रोमक) लोगों में भी यह सिक्का दिनारियस के नाम से प्रचलित था।

यह एक स्त्री का सिर था जो 3000 ई . पू . में उरुक नगर में संगमर्मर को तराश कर बनाया गया था । इसकी आंखों और भौंहों में नीले लाजवर्त तथा सफेद सीपी और काला डामर की जड़ाई की गई थी । सिर के ऊपर खांचा बना हुआ है जो शायद गहना पहनने के लिए बनाया गया था । यह मूर्ति कला का एक विश्व प्रसिद्ध नमूना है ।
