a neutral atom of chlorine (CI) has an average mass of 35 amu and 17 electrons. How many neutrons does it have?

Respuesta :

Number of neutrons is 35-17=18.

Answer:

it would have 18 neutrons, as a neutral atom has the same number of electrons as protons, therefore the number of protons is 17. 35-17 leaves you with 18 neutrons
