Answer
Explanation:
Step1: Recall Chlorine's properties
Chlorine has atomic number 17. In a neutral atom, number of protons = number of electrons = 17. The most common isotope of chlorine has a mass - number of 35. Mass - number = number of protons+number of neutrons. So number of neutrons = 35 - 17=18. Total number of particles = protons + electrons+neutrons = 17 + 17+18 = 52. Chlorine is in group 17 and period 3.
Step2: Recall Argon's properties
Argon has atomic number 18. In a neutral atom, number of protons = number of electrons = 18. Given number of neutrons = 22. Total number of particles = 18 + 18+22 = 58. Argon is in group 18 and period 3.
Answer:
| Element | # of Protons | # of Electrons | # of Neutrons | Total Number of Particles | Group | Period |
|---|---|---|---|---|---|---|
| Chlorine | 17 | 17 | 18 | 52 | 17 | 3 |
| Argon | 18 | 18 | 22 | 58 | 18 | 3 |
