Current Question (ID: 20932)

Question:

$\text{Mark the correct increasing order of the metallic character of the given below elements:}$ $\text{Si, K, Mg, and Be}$

Options:

1. $\text{Si} < \text{Mg} < \text{Be} < \text{K}$
2. $\text{Be} < \text{Mg} < \text{Si} < \text{K}$
3. $\text{Si} < \text{Be} < \text{Mg} < \text{K}$
4. $\text{K} < \text{Mg} < \text{Si} < \text{Be}$

Solution:

$\text{Hint: Metallic character is inversely related to the metallic character.}$ $\text{Explanation:}$ $\text{Metallic character refers to the level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies.}$ $\text{Within a compound, metal atoms have a relatively low attraction for electrons. This is indicated by their low electronegativities.}$ $\text{Based on the electronegativity of the given elements, the correct increasing order of metallic character is:}$ $\text{Si} < \text{Be} < \text{Mg} < \text{K}$ $\text{Electronegativity of:}$ $\text{Si} = 1.90$ $\text{Be} = 1.57$ $\text{Mg} = 1.31$ $\text{K} = 0.82$ $\text{Thus, the correct option is 3.}$
