I'm looking for the missing information in the table
number of protons-36
number of neutrons-42
number of electrons-
The number of protons in 37 Cl is 17. What's confusing is I don't know what the 36 46 means.
The number of neutrons is 37-17 = 20. I don't understand the 42.
The number of electrons is 17.
The mass number is 37. I don't understand the 77 106.
