1.	Which of the following statements are not true for hydrogen ?A. It exist as diatomic moleculeB. It has one electron in the outermost shellC. It can lose an electron to from a cation which can freely existD. If from a large number of ionic compounds by losing an electron
Answer» Correct Answer - C::D `H^(+)` does not exist freely and is always associated with other atoms or molecules. Like alkali metals, hydrogen forms oxides, halides and sulphides. However, unlike alkali metals, it has very high ionisation enthalpy and does not possess metallic characteristics under noraml conditions.
