Answer:
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.
