[@souravsaha2940]

যেহেতু এগুলো রেকর্ডেড ক্লাস তাই ক্লাস গুলোর মাঝে পড়া বোঝানোর মধ্যে কিছু কিছু অংশ আপনারা কেটে দেন 20:06 এমনটা করলে আমাদের তো বুঝতে অসুবিধা হচ্ছে

[@anweshabanerjee2308]

nitrogen gases are most abandont in atmosphere & can not be taken upby plant & animals as it can not be synthesized directly in the soil..it requires help of several bacteria to synthesize it

[@NasrinaKhatun-h5y]

Very effective class sir ji.. thank you so much

nitrogen is not used for breathing although it is found in 78 percent in the highest amount in the atmosphere because it is an inert gas.

[@snehasaha5157]

Nitrogen gas does not get bind with blood because it does not have Nitrogen binding protein complex to binding Nitrogen. Human have unable to inhale Nitrogen because it is an inert gas and consists of triple bond which is unreactive Nitrogen is unable to break after breathing.

Atomic Model একটা Completely Quantum Mechanical Problem ... Classical Physics এর সাথে এর Theory এর ক্ষেত্রে Applicable নয়। Content এ যেটা বলা আছে , সেটা in general pattern ... Even এটাও বলা আছে যে , n ( integer no ) = 4 পর্যন্তই existence পাওয়া গেছে , বা আমাদের প্রতিযোগিতামূলক পরীক্ষার ক্ষেত্রেও ওটাই আসে শুধু। কিন্তু কিন্তু , আপনি একটু পড়াশোনা করলেই জানতে পারবেন Quantum Mechanical Model ( 1924 ) অনুযায়ী g এবং h subshell er existence আছে বলে Predict করা গেছে। যেখানে যথাক্রমে 18 ও 22 টি করে ইলেকট্রন থাকবে। সেক্ষেত্রে একই প্যাটার্ন অনুযায়ী 5th , 6th ও 7th Subshell এ 50 , 72 এবং 98 টি করে ইলেকট্রন থাকবে। এখনো পর্যন্ত পর্যায় সরণিতে 118 ( Og ) টি মৌল আবিষ্কার হয়েছে। তাই In Practical g বা h subshell এর Exsitence খুঁজে পাওয়া যায়নি। কিন্তু 126 তম মৌল আবিষ্কার হলে তার Electronic Configuration করতে গেলে g Subshell প্রয়োজন পড়বে। তবে কিছু মৌলের ক্ষেত্রে ground state e f orbital এ ইলেকট্রন থাকলেও , 1st exited state e g orbital এ Electronic transition হয়। যেমন , • Element 126: [Og] 8s2 8p1 6f4 5g¹ element 127: [Og] 8s2 8p2 6f3 5g2 element 128: [Og] 8s2 8p2 6f3 5g3 element 129: [Og] 8s2 8p2 6f3 5g4 element 130: [Og] 8s2 8p2 6f3 5g5 element 131: [Og] 8s2 8p2 6f3 5g6 কিন্তু সবটাই Quantum mechanical Model এর Hypothesis.. & Content এ যেটা দেখানো হয়েছে , সেটা In general pattern.. WBCS পরীক্ষার ক্ষেত্রে এতটা দরকার হয়না বলে বলা হয়নি। এবং কোনটুকু পড়তে হবে , সেটাও মার্কিং করে দেখানো আছে , এবং বলাও আছে। আশা করি ওরা বুঝতে পারবে। ধন্যবাদ।
