A, B and C are magnesium, aluminium and silicon. Magnesium forms ionic oxide, (MgO) aluminium forms amphoteric oxide, (Al2O3) and silicon forms a giant molecule (SiO2).

Q. $(A)$ , $(B)$ and $(C)$ are elements in the third short period. Oxide of $(A)$ is ionic, that of $(B)$ is amphoteric and of $(C)$ a giant molecule. $(A)$ , $(B)$ and $(C)$ have atomic number in the order :

$(A) < (B) < (C)$

$(C) < (B) < (A)$

$(A) < (C) < (B)$

$(B) < (A) < (C)$

$A$ , $B$ and $C$ are magnesium, aluminium and silicon. Magnesium forms ionic oxide, $(M g O)$ aluminium forms amphoteric oxide, $(A l_{2} O_{3})$ and silicon forms a giant molecule $(S i O_{2})$ .

Q. (A), (B) and (C) are elements in the third short period. Oxide of (A) is ionic, that of (B) is amphoteric and of (C) a giant molecule. (A), (B) and (C) have atomic number in the order :

(A)<(B)<(C)

(C)<(B)<(A)

(A)<(C)<(B)

(B)<(A)<(C)
