Question

which two elements will react to form a salt, such as common table salt
alkali metal and halogen
two transition metals
two alkali earth metals
transition metal and halogen

Answer 1

To form a salt like common table salt (sodium chloride, NaCl), you need an alkali metal and a halogen. Therefore, the correct answer is:

**alkali metal and halogen**.

In this case, the alkali metal (e.g., sodium) reacts with a halogen (e.g., chlorine) to form the salt.
