Question

$Na\stackrel{-1electron}{\to }N{a}^{+}$
Unstable sodium atom is converted to stable sodium ion. The formation of sodium ion describes the concept of______________.

• A. electronegativity
• B. electropositivity
• C. radicals
• D. electron energy

Answer 1

The correct option is B electropositivity

During chemical combination, an atom donates electrons to acquire a stable electronic configuration and thus becomes a positively charged ion. Sodium atom turns into sodium ion due to the nature of electropositivity,which means the atom is ready to donate an electron to gain stability. Electronegativity is a nature of the element which accepts electrons to attain stability and a radical is defined as an element which collectively accepts or donates one or more electrons and become negatively or positively charged in the process.
