Which participates in chemical reactions? (3 points)ProtonsNeutronsElectronsGamma rays

In chemical reactions, the primary participants are electrons. Here's a detailed explanation:

1. Electrons: These are negatively charged subatomic particles that orbit the nucleus of an atom. They play a crucial role in forming chemical bonds between atoms. During a chemical reaction, electrons can be transferred or shared between atoms, leading to the rearrangement of atoms and the formation of new substances.

2. Protons: While protons are positively charged particles found in the nucleus of an atom and determine the element's identity, they do not participate directly in chemical reactions. The number of protons in an atom remains constant during such reactions.

3. Neutrons: Neutrons are neutral particles also located in the nucleus. Like protons, they do not participate in chemical reactions. Their main role is to stabilize the nucleus of an atom.

4. Gamma Rays: These are high-energy electromagnetic waves emitted by radioactive substances or other high-energy processes. Although they are a form of energy, they do not take part in chemical reactions.

In summary, among the given options, electrons are the primary participants in chemical reactions.
