Question

use the sodium (na) and chlorine (cl) atoms for this next activity. both atoms have a neutral charge by themselves. explore it! part 4 move the single electron from sodium (na) to where you think it belongs in the chlorine (cl) model. 1. explain why you chose to place the electron there. your answers: 8. answer here go to part 5

Explanation:

Chlorine has 7 electrons in its outer - shell. According to the octet rule, atoms tend to gain, lose or share electrons to have 8 electrons in their outer - shell for stability. Sodium has 1 electron in its outer - shell. By moving the single electron from sodium to chlorine, chlorine will have 8 electrons in its outer - shell (7 + 1), achieving a stable electron configuration.

Answer:

The electron is placed in chlorine's outer - shell because chlorine needs one more electron to complete its octet (have 8 electrons in its outer - shell) and achieve a stable electron configuration as per the octet rule.
