Explanation The total number of electrons in the Lewis structure is obtained by the addition of the valence electrons of each atom present in the molecule. For Example: number of electrons in formaldehyde: H 2 C O can be obtained as: T o t a l n u m b e r o f e l e c t r o n s f o r L e w i s s t r u c t u r e = 2 ( n u m b e r o f v a l e n c e e l e c t r o n s o f H ) + ( n u m b e r o f v a l e n c e e l e c t r o n s o f C ) + ( n u m b e r o f v a l e n c e e l e c t r o n s o f O ) Interpretation Introduction To determine: The number of electrons in the Lewis structure of a polyatomic ion.
