The species is 3517Cl. The atomic number is 17, so a neutral Chlorine atom has 17 protons and 17 electrons. We need to find the species with 17 electrons. A) 3216S: Atomic number 16. Neutral Sulfur has 16 electrons. B) 3416S+: Atomic number
The species that has the same number of electrons as 35 17Cl is

- Neutral Sulfur has 16 electrons. S⁺ means it lost 1 electron (16 - 1 = 15 electrons). C) 4018Ar+: Atomic number 18. Neutral Argon has 18 electrons. Ar⁺ means it lost 1 electron (18 - 1 = 17 electrons). D) 3516S2-: Atomic number 16. Neutral Sulfur has 16 electrons. S²⁻ means it gained 2 electrons (16 + 2 = 18 electrons). Therefore, 4018Ar+ has 17 electrons, the same number as neutral 3517Cl. These species are isoelectronic. 51. The atomic number of an element is 8.
