Question

question 38 using the diagrams below: if cl interacted with na, cl would? 17: chlorine 2,8,7 10: neon 2,8 11: sodium 2,8,1 a. lose two electrons b. not interact as it is stable c. gain two electrons d. gain an electron

Explanation:

Step1: Analyze chlorine's valence electrons

Chlorine (Cl) has 7 valence electrons. Its electron - configuration in the outermost shell is 2,8,7. It wants to achieve a stable octet configuration.

Step2: Analyze sodium's valence electrons

Sodium (Na) has 1 valence electron. Its electron - configuration in the outermost shell is 2,8,1. It tends to lose this 1 electron to achieve a stable octet in its inner shell.

Step3: Determine the reaction

When Cl interacts with Na, Na will lose its 1 valence electron and Cl will gain that electron to complete its octet.

Answer:

d. gain an electron
