a halogen and a noble gas

Answer 1

The correct response is: an alkali metal and a halogen.

In this type of chemical reaction, alkali metals (such as sodium or potassium) tend to lose an electron and form positive ions, while halogens (such as chlorine or fluorine) gain an electron to form negative ions. This transfer of electrons is characteristic of ionic bonding between these two groups of elements.
