Why is lithium not in the electro positive series

Answer 1

Lithium is actually considered to be a part of the electro positive series because it is an alkali metal with a single valence electron, which makes it highly reactive and capable of easily losing that electron to form a positive ion (Li+). This property is characteristic of electro positive elements, which have a tendency to lose electrons and form positive ions.

The electro positive series is a list of elements arranged in order of their tendency to lose electrons and form positive ions. However, it is important to note that the electro positive series can vary depending on the specific context or criteria used for determining electronegativity.

It is possible that some sources or contexts may exclude lithium from the electro positive series due to its relatively higher electronegativity compared to other elements in the series. Electronegativity is a measure of an element's tendency to attract electrons towards itself in a chemical bond. While lithium is highly electro positive, its electronegativity value is higher compared to other elements such as sodium or potassium, which may lead to variations in the inclusion of lithium in the electro positive series.
