Solution

Atomic number: The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom.
Atomic number = number of protons = number of electrons
Given, Atomic number = 17
Therefore, Number of electrons = Number of protons = 17
