Quizplus · Accepted Answer

The atomic number represents the number of protons in the nucleus of an atom. As the given atom is Cl with an atomic number of 17, it has 17 protons.
The mass number of the atom can be calculated by adding the number of protons and neutrons in the nucleus. The given atom has a mass number of 35, which indicates that it has 18 neutrons (35 - 17 = 18).
To determine the number of electrons, we can look at the charge of the ion if it is an ion. However, there is no indication in the question that it is an ion. Therefore, we can assume that it is a neutral atom, which means it has the same number of electrons as protons. So, the given atom has 17 electrons. 
Hence, the correct option is D.
