What is the process called when two or more atoms join together chemically?

1. Combination

2. Synthesis

3. Formation

4. Bonding

The correct answer is: Synthesis

The process in which two or more atoms join together chemically is known as synthesis. This term specifically refers to the chemical reaction in which simpler substances combine to form more complex molecules or compounds. In the context of chemistry, synthesis is essential as it encompasses various types of reactions where different atoms are bonded together to create new chemical structures. While the other terms relate to aspects of chemical reactions or interactions, they do not precisely describe the process of atoms combining to form compounds. For instance, "combination" may suggest the joining of elements but is not as specific to the chemical synthesis process. "Formation" often refers to the creation of a particular structure but lacks the clarity of chemical bonding contexts. "Bonding" generally describes the force that holds atoms together rather than the actual process of atoms coming together to create new substances, which is thoroughly captured by the term synthesis. Thus, synthesis accurately encompasses the idea of atoms joining chemically to form new compounds, making it the most precise answer to the question.
