WebNov 11, 2024 · The electronegativity of Magnesium is: χ = 1.31. In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it.
