(i) O and F exist as a monoatomic gases |
(ii) is the lightest element in the period |
(iii) B is a metalloid while C is a metal. |
(iv) Li and F react to form a compound LiF. |
A) (i) and (iii) only
B) (ii) and (iv)only
C) (ii) and (iii) only
D) (i) and (iv) only
Correct Answer: B
Solution :
Q and F exist as diatomic gases, \[{{O}_{2}}\] and \[{{F}_{2}}\]respectively. Li is the lightest element of the second period having atomic mass 6.9. B is a metalloid while C is a non-metal. Li and F react to form an ionic compound, LiF. \[L{{i}^{+}}+{{F}^{-}}\xrightarrow{{}}LiF\]You need to login to perform this action.
