an alkali metal and a halogen

Answer 1

The correct response is **an alkali metal and a halogen**. This is because alkali metals (such as sodium or potassium) typically lose one electron to achieve a stable electronic configuration, while halogens (such as chlorine or fluorine) typically gain one electron to complete their outer shell and also achieve stability.
