The property of hydrogen which distinguishes it from alkali metals isa...
Explanation:
Hydrogen is often placed in the same group as alkali metals because it has one valence electron like them, but it is different from them in many ways. The property that distinguishes hydrogen from alkali metals is its non-metallic character.
Reasons why hydrogen is a non-metal:
1. Electronic Configuration: Hydrogen has only one electron in its valence shell, which is similar to the alkali metals, but hydrogen differs from them because the electron is in the 1s orbital, which is the same as the noble gases. This electronic configuration makes hydrogen behave differently from the alkali metals.
2. Electronegativity: Hydrogen has a high electronegativity, which is a characteristic of non-metals. Electronegativity is the ability of an atom to attract electrons towards itself. Alkali metals have low electronegativity because they tend to lose electrons easily.
3. Physical Properties: Hydrogen is a gas at room temperature, which is another characteristic of non-metals. Alkali metals are solids at room temperature. Hydrogen has a low boiling and melting point, which is also typical of non-metals.
4. Chemical Properties: Hydrogen is a poor conductor of heat and electricity, which is a property shared by non-metals. Alkali metals, on the other hand, are good conductors of heat and electricity.
Conclusion:
Thus, the non-metallic character of hydrogen distinguishes it from alkali metals.
