A or possibly C because the other options have nothing to do with the size of the vibration. If i was you I would answer with A
You should’ve ate the cat , that’s the only reasonable way to get revenge :)
Answer: Option (C) is the correct answer.
Explanation:
Sodium has atomic number 11 and its electronic distribution is 2, 8, 1. Whereas chlorine has atomic number 17 and its electronic configuration is 2, 8, 7.
Therefore, we can see that sodium has one extra electron and chlorine has deficiency of one electron.
So, in order to complete their octet sodium will give its one valence electron to the chlorine atom. Hence, there is exchange of electrons and thus it will result in the formation of ionic bond.
Thus, we can conclude that in sodium chloride electron movement is related to the bonding as electrons exchange creating ions to form an ionic bond by electrostatic attraction.
