Question

Electron density can be determined on the basis of which among the following options?

• A. Atomic mass
• B. Atomic number
• C. Atomic radius
• D. Electronegativity
• E. DIonization potential

Answer 1

The correct option is D Electronegativity

Electron density can be determined on the basis of electronegativity.
Electronegativity, symbol $\chi$, is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
