The group of elements with the most similar chemical properties among the options provided is **magnesium, strontium, and radium**.
This is because magnesium (Mg), strontium (Sr), and radium (Ra) are all in Group 2 of the periodic table, also known as the alkaline earth metals. Elements in the same group have similar chemical properties due to their similar electron configurations.
The other groups consist of elements that belong to different groups on the periodic table and therefore exhibit more varied chemical properties:
- **Hydrogen, helium, and lithium** are from different groups (hydrogen is a nonmetal, helium is a noble gas, and lithium is an alkali metal).
- **Nitrogen, oxygen, and fluorine** are part of different groups (nitrogen is a group 15 element, oxygen is group 16, and fluorine is group 17).
- **Phosphorus, sulfur, and chlorine** are also from different groups (phosphorus is group 15, sulfur is group 16, and chlorine is group 17).
Hence, the elements in the first group (magnesium, strontium, and radium) share the most similar chemical properties.
