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)

Question

two alkaline earth metals

an alkali metal and a halogen

a halogen and a noble gas

two halogens

Answer 1

The example of a chemical reaction where atoms of one element each lose an electron while atoms of another element each gain an electron describes an ionic bond formation. In this context, the correct pair of elements would be:

an alkali metal and a halogen.

Alkali metals (such as sodium or potassium) tend to lose one electron, while halogens (such as chlorine or fluorine) tend to gain one electron to achieve a stable electron configuration.
