Here are the answers to your questions:
1. **Which of the following is a negatively charged ion (not a polyatomic ion)?**
- **Answer:** **chloride** (Cl⁻ is the negatively charged ion form of chlorine)
2. **When moving across a period from left to right in the periodic table (excluding transition elements) which trend occurs?**
- **Answer:** **Valence electrons increase by one.**
3. **Which information about an atom can a period number give you?**
- **Answer:** **how many energy levels it has.** (The period number indicates the principal energy level of the valence electrons.)
4. **Fluorine has 7 valence electrons. Which charge is its ion likely to have?**
- **Answer:** **1–** (Fluorine tends to gain one electron to achieve a full octet, resulting in a charge of -1.)
5. **Which two elements in the list would bond together based on their ionic charges?**
- **Answer:** **potassium and iodine** (Potassium (K) typically forms a +1 ion and iodine (I) typically forms a -1 ion, so they would bond to form KI.)
If you have any more questions or need further clarification, feel free to ask!
