Which particle is responsible for the chemical properties of an atom? (2023)

Step 1: Understand that atoms are made up of three main particles: protons, neutrons, and electrons.
Step 2: Know that protons and neutrons are found in the nucleus (center) of the atom.
Step 3: Learn that electrons are found in shells or energy levels around the nucleus.
Step 4: Focus on the outer shell of electrons, which are called valence electrons.
Step 5: Realize that the number and arrangement of these valence electrons determine how an atom interacts with other atoms.
Step 6: Conclude that the chemical properties of an atom, such as how it bonds with other atoms, are mainly influenced by its outer shell electrons.
