The correct answer is:
**A. A Lithium atom forms a Li+1 ion by losing one electron.**
Here's a brief explanation for each option:
- **A.** True. Lithium (Li) has 3 electrons. When it loses one electron, it forms a Li+1 ion.
- **B.** False. Fluorine (F) has 7 electrons. It gains one electron to form the F-1 ion, not loses one.
- **C.** False. Magnesium (Mg) has 12 electrons. It loses two electrons to form the Mg+2 ion, not gains three.
- **D.** False. Phosphorus (P) typically gains three electrons to form the P-3 ion, not loses three.
Thus, option A is the only correct statement.
