To analyze the given information about the atom with 17 protons (p) and 18 neutrons (n), let's break down the statements:
1. **Mass of the atom is 35 AMU.**
- The mass number is the sum of protons and neutrons. In this case, \(17 \text{ protons} + 18 \text{ neutrons} = 35\). Thus, this statement is **true**.
2. **Atomic number of this atom is 18.**
- The atomic number is equal to the number of protons. Since this atom has 17 protons, the atomic number is **17**, not 18. So, this statement is **false**.
3. **This is a chlorine atom.**
- Chlorine has an atomic number of 17, which matches the number of protons in this atom. Therefore, this statement is **true**.
4. **The atom has an overall charge of 0.**
- If an atom has an equal number of protons (positive charge) and electrons (negative charge), it will have a net charge of 0. This atom has 17 protons; assuming it has 17 electrons, it will indeed have an overall charge of 0. Thus, this statement is **true**.
Given this analysis, the FALSE statement is:
- **The atomic number of this atom is 18.**
1. **Mass of the atom is 35 AMU.**

3. **This is a chlorine atom.**
- Chlorine has an atomic number of 17, which matches the number of protons in this atom. Therefore, this statement is **true**.
4. **The atom has an overall charge of 0.**
- If an atom has an equal number of protons (positive charge) and electrons (negative charge), it will have a net charge of 0. This atom has 17 protons; assuming it has 17 electrons, it will indeed have an overall charge of 0. Thus, this statement is **true**.
Given this analysis, the FALSE statement is:
- **The atomic number of this atom is 18.**
