What happens when the compound nacl is formed?

a. sodium transfers an electron to chlorine.
b. sodium receives two electrons from chlorine.
c. sodium forms an ion with −1 charge and chlorine forms an ion with +1 charge.
d. sodium forms an ion with +2 charge and chlorine forms an ion with −2 charge.

A. Sodium transfers an electron to chlorine

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

NaCl, or more commonly known as table salt, is formed with Sodium Na and Chlorine Cl.

The oxidation for Na is Na⁺ ion (sodium wants to lose an e⁻ to stabilize its outermost shell) and the oxidation for Cl is Cl⁻ ion (chlorine wants to gain an e⁻ to stabilize its valence shell).

Na would transfer its electron to chlorine and form an ionic bond and compound. Na would now lose its electron and have a stable shell while Cl would now gain an electron and have a stable shell.

Therefore, our best answer choice is A.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
