has 37 electrons in the orbit about its nucleus.
Atomic mass is the total number of neutrons and protons present in the nucleus of an element.
The atomic number is the total number of protons present in the nucleus of an element.
For writing an atomic symbol, atomic mass is written on the top left of the atomic symbol, and the atomic number is written on the downside of the left of the symbol.
An electrically neutral atom is an atom that has an equal number of electrons as well as protons.
Thus from the above conclusion we can say that has 37 electrons.
