Answer:
Chlorine(Cl) is a bit more negative than Sodium(Na)
Explanation:
Cl has an electronegativity of 3.0
Na has an electronegativity of 1.0
Answer:
The bond between Na & CI is ionic. One atom will form a a negative ion and the other will form a positive ion. Sodium (Na) has 1 valence electron, so it will give it away in order to become stable (octet rule). Chlorine has 7 valence electrons. So when Na and Cl bond, chlorine will take sodium's 1 valence electron and become stable. Now both atoms are stable but each form a specific ion. Since sodium lost its electron, It now has an imbalance where there are more protons than neutrons. This makes the sodium atom a positively charged ion (Na+). Since chlorine gained an electron, it now has an inbalance where there are more electrons than protons. This makes the atom a negatively charged ion (Cl-)
