Question

Find the values of 'a' in equation ′ ( a + 0.30 ) + 0.65 ( n − 1 ) ′ which gives the value of effective nuclear charge experience by last electron of 2 nd period element. (where n is number of electrons in 2 nd shell)

E : 1 s 2 ( 2 s 2 p ) n Z e ff ​ = ( n + 2 ) − [ 2 × 0.85 + ( n − 1 ) × 0.35 ] A t o mi c n u mb er Z e ff ​ = n + 2 − 1.70 − 0.35 ( n − 1 ) Z e ff ​ = ( n − 1 ) + 1 + 0.30 − 0.35 ( n − 1 ) Z e ff ​ = 1 + 0.30 + 0.65 ( n − 1 ) So, a = 1 .
