Answer:
In conclusion, we have:
17 protons
18 electrons
20 neutrons
Step-by-step explanation:
Hello!
Let's solve this!
The atomic number indicates the number of protons that is equal to the number of electrons.
In this case, the number of protons is equal to 17.
The number of electrons is equal to 17.
To calculate the number of neutrons, we subtract the mass:
37-17 = 20.
Since the mass is equal to the number of neutrons plus that of protons.
In this case, the number of neutrons is 20.
As it has a charge -1, we add one more electron.
In conclusion, we have:
17 protons
18 electrons
20 neutrons
