Lets discuss our questions regarding chemistry

when do you guys have the exam tomorrow?

[nadinesujud]

oh me too

i have a questionnn
it says
suggest a reason why NaCl vapour is regarded as a collection of ion pairs rather than as NaCl molecules?

 

[Alzaabi]

because NaCl is a form of ionic bond. A molecule is the smallest part of a Covalent bond. therefore its a collection of ion pairs rather than molecules.
