For the second period elements the correct increasing order of first io0nization enthalpy is:
A
Li lt Be lt B lt C lt N lt C lt Flt Ne
B
Li lt B lt Be lt C lt O lt N lt F lt Ne
C
Li lt B lt Be lt C lt N lt O lt F lt Ne
D
Li lt Be lt B lt C lt O lt N lt F lt Ne
Text Solution
Verified by Experts
The correct Answer is:
B
.Be. and .N. have comparatively more stable valence sub shell then .B. and .O.. Generally lonisation energies increases across a period. Thus, correct increasing order of first ionisation enthalpy is: Li < B < Be < C < O < N < F < Ne
