The metals will lose electrons while the non metals will gain electrons in order to attain octet structure.

An ion can be cation (positively charged) or anion (negatively charged).

Cations attain octet structure (8) by losing electron(s) while anions become stable or attains octet structure (8) by gaining electron(s).

The remaining elements are completed as follows to attain octet structure;

<u>Element</u>--<u>valence electron</u>--<u>electrons to gain</u>--<u>electrons to lose</u>--<u>ion formed</u>

O ------------ 6 ----------------------  2 ------------------------  none -------------- O^{2-}

Ca --------   2 ----------------------- none ---------------------- 2 ------------------ Ca^{2+}

Br ----------- 7 ---------------------     1 ------------------------ none --------------- Br^{-}

S ------------ 6 -----------------------  2 ------------------------ none --------------- S^{2-}

Cl ------------ 7 -----------------------  1 ------------------------ none ----------------Cl^{-}

Nicotine is a toxic substance present in tobacco leaves. There are two lone pairs in the structure of nicotine. In general, loca
Harlamova29_29 [7]

Answer:

B.Lone pair in pyrrolidine ring is localized and, therefore, is expected to be more reactive.

Explanation:

There are two nitrogen atoms bearing lone pairs of electrons in the structure of nicotine as shown in the image attached.

One nitrogen atom is found in the pyrrolidine ring. The lone pair on this nitrogen atom is localized hence it is more reactive than the lone pair of electrons found on the nitrogen atom in the pyridine ring which is delocalized a shown in the image attached to this answer.
