![]() The magnesium ion has charge of 2+ while Na has a charge of 1+, this would mean that the there is stronger attraction between the valence electrons of Mg than the valence electrons of Na. (For this you need to consider only the net charge of the ions formed as the charge would be considered neutral once electrons and protons are equal). ![]() There are also other cases in the reactivity series that are explained in a similar way. The reaction would tend to occur more readily hence the reactivity of potassium is higher than sodium. The potassium would have a lower tendency of attracting electrons compared to sodium, it would hence more readily lose electrons to form potassium ions (K+) to form ionic bonds with other elements. However, as you said the reactivity series says potassium is more reactive than sodium. ![]() Here is a visual explanation of the situation.Īs the atoms move from left to right, the electronegativity of these atoms are decreasing as the distance between the electrons and the positively charged nucleus is would be greater, giving it lower ability to attract electrons. ![]() Whereas an element's reactivity is based more on how ready it is to gain or lose electrons. 1 An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. ![]()
