Alkali metal exist in form of
Correct answer: C. Both silicates and individual form
- A. Silicates
- B. Individual form
- C. Both silicates and individual form
- D. None
Explanation
Alkali metals, due to their high reactivity, are rarely found in their pure elemental form. They are commonly found as part of silicate minerals, which are compounds that include silicon and oxygen. These metals can sometimes be found in their pure form in certain mineral deposits but only in trace amounts. This dual existence is due to their reactivity, which allows them to bond easily with other elements such as silicon and oxygen. Therefore, the correct answer is that alkali metals exist in both silicate and individual forms. Other options are incorrect because they do not represent the complete set of natural occurrences of alkali metals.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
