Question

1. form a bond: each electron has a charge of 1-, and each proton has a charge of 1+. you can calculate the charge of an atom by subtracting the number of electrons from the number of protons. move an electron from the sodium to the chlorine atom.

a. what are the charges of each atom now? sodium: chlorine:
turn on show charge to check. these charged atoms are called ions.
b. is each ion stable? explain.

Explanation:

Step1: Determine the charge of sodium

Sodium has 11 protons. After losing 1 electron (now has 10 electrons), charge = \(11 - 10=1+\)

Step2: Determine the charge of chlorine

Chlorine has 17 protons. After gaining 1 electron (now has 18 electrons), charge = \(17 - 18 = 1-\)

Step3: Check stability

Sodium ion (\(Na^{+}\)) has a full outer shell (2 - 8 configuration). Chloride ion (\(Cl^{-}\)) has a full outer shell (2 - 8 - 8 configuration).

Answer:

A. Sodium: \(1+\), Chlorine: \(1-\)
B. Yes. Sodium ion (\(Na^{+}\)) has a full outer shell (2 - 8 configuration). Chloride ion (\(Cl^{-}\)) has a full outer shell (2 - 8 - 8 configuration).
