The electronic configuration of a metallic element plays a significant role in determining its reactivity with non-metallic elements in forming inorganic compounds. This reactivity is primarily influenced by the ease with which a metallic element can lose its valence electrons to form positive ions cations and the ability of non-metallic elements to gain electrons to form negative ions anions . The process of electron transfer leads to the formation of ionic bonds, which are the basis of inorganic compounds.Here are some factors related to electronic configuration that affect the reactivity of metallic elements:1. Number of valence electrons: Metallic elements with fewer valence electrons 1 or 2 tend to be more reactive because they can easily lose these electrons to achieve a stable electronic configuration. For example, alkali metals Group 1 and alkaline earth metals Group 2 are highly reactive due to their low number of valence electrons.2. Energy levels: The reactivity of metallic elements decreases as we move across a period in the periodic table. This is because the number of energy levels shells increases, and the valence electrons are further away from the nucleus. As a result, the attraction between the nucleus and the valence electrons decreases, making it more difficult for the metallic element to lose its valence electrons.3. Effective nuclear charge: The effective nuclear charge Zeff is the net positive charge experienced by the valence electrons. As we move across a period, the Zeff increases due to the increase in the number of protons in the nucleus. This increase in Zeff results in a stronger attraction between the nucleus and the valence electrons, making it harder for the metallic element to lose its valence electrons and react with non-metallic elements.4. Ionization energy: Ionization energy is the energy required to remove an electron from an atom. Metallic elements with lower ionization energies are more reactive because they can easily lose their valence electrons. For example, alkali metals have low ionization energies, making them highly reactive with non-metallic elements.In summary, the electronic configuration of a metallic element affects its reactivity with non-metallic elements in forming inorganic compounds by influencing the ease with which it can lose its valence electrons. Factors such as the number of valence electrons, energy levels, effective nuclear charge, and ionization energy play crucial roles in determining the reactivity of metallic elements.
