Hello sir Order of EA in 2nd period should be : Ne < Be < N < B < Li < C < O < F Because sir Be ----> 1s2 2s2 (nobel gas config.) N -----> 1s2 2s2 2p3 Half filled and fully filled ki EA wese bhi low hoti h usme bhi fully filled ki half filled se low EA hoti. So why you write N < Be Also Li > B Li --> 1s2 2s1 ( half filled) B --> 1s2 2s2 2p1 ( partially filled) Penetration effect Plz explain sir I'm confused

FIITJEE student here , they took 5 lectures( less than 10 hr ) to cover such a vast chapter like NLM . I feel that these online lectures are so many times better than these "reputed" coachings..
