Verified step by step guidance1
Begin by understanding the structure of an atom. An atom consists of a nucleus, which contains protons and neutrons, and electrons that orbit around the nucleus.
Recognize that protons are positively charged particles found in the nucleus, and they define the atomic number of an element, but they do not directly influence chemical properties.
Understand that neutrons are neutral particles also located in the nucleus. They contribute to the atomic mass but do not affect the chemical properties of an atom.
Identify that electrons are negatively charged particles that orbit the nucleus in various energy levels or shells. They are involved in forming chemical bonds and interactions, which determine the chemical properties of an atom.
Conclude that the chemical properties of an atom are primarily determined by the arrangement and behavior of electrons, as they participate in chemical reactions and bonding.
