Question 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 two alkaline earth metals two alkaline earth metals two halogens two halogens an alkali metal and a halogen an alkali metal and a halogen a halogen and a noble gas

Answer 1

In the scenario described, where atoms of one element lose electrons and atoms of another element gain electrons, the two elements involved are likely an alkali metal and a halogen.

Alkali metals (such as sodium or potassium) readily lose one electron to achieve a stable electronic configuration, while halogens (such as chlorine or bromine) readily gain one electron to achieve stability. This transfer of electrons leads to the formation of ionic compounds.

Therefore, the correct response is an alkali metal and a halogen.
