Why sodium is more electropositive than chlorine?​

Electronegativity is high because the halogen has a large, unshielded nuclear charge. Sodium is a metal and metals tend to be low in electronegativity

Explanation: Halogen has a large, unshielded nuclear charge which is why the electronegativity is high. Sodium is metal so it tends to be low in electronegativity.

Explanation:

This electropositivity is high because the halogen has a large, unshielded nuclear charge. Sodium is a metal and metals tend to be low in electronegativity (they like to give away their electrons). Chlorine, similar to oxygen, likes to take and keep electrons.

i don,t know so just answer mine
