The correct response is an alkali metal and a halogen. In this type of reaction, alkali metals (such as sodium or potassium) lose one electron to achieve a stable electronic configuration, while halogens (such as chlorine or fluorine) gain an electron to achieve stability. This transfer of electrons results in the formation of ionic compounds.
In an example of a chemical reaction, atoms of one element each lose an electron. Atoms of another element each gain an electron. What could be the two elements? (1 point) Responses an alkali metal and a halogen an alkali metal and a halogen two halogens two halogens a halogen and a noble gas a halogen and a noble gas two alkaline earth metals
