* Protons: Positively charged particles located in the atom's nucleus.
* Neutrons: Neutrally charged particles also located in the nucleus.
* Electrons: Negatively charged particles that orbit the nucleus in a cloud of probability called an electron cloud.
Here's a breakdown:
* Nucleus: The central core of an atom, containing protons and neutrons. This is where the majority of the atom's mass is concentrated.
* Electron Cloud: The region surrounding the nucleus where electrons are found. Electrons are constantly moving and their exact location cannot be pinpointed. Instead, we describe their probable locations in the electron cloud.
Key Points:
* Atomic Number: The number of protons in an atom defines its atomic number. This number determines what element the atom is.
* Atomic Mass: The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus.
* Isotopes: Atoms of the same element can have different numbers of neutrons. These are called isotopes. While they are the same element (same atomic number), they will have different atomic masses.
