Study Notes
Fundamental Particles in the Nucleus
- The nucleus of an atom is primarily composed of two types of particles: protons and neutrons.
- Protons carry a positive charge, while neutrons are electrically neutral.
Collective Term for Nucleus Particles
- Protons and neutrons are collectively referred to as nucleons.
Structure of the Atom
- The central region of an atom is known as the nucleus, which is densely packed and contains most of the atom's mass.
Role of Electrons
- Electrons are negatively charged particles that orbit the nucleus, playing a crucial role in chemical bonding and interactions.
- They determine the atom's reactivity and properties by influencing its ability to form bonds with other atoms.
Arrangement of Nucleons
- Protons and neutrons are tightly packed within the nucleus, held together by the strong nuclear force.
- The specific arrangement can vary in different elements, which contributes to their unique atomic structure and stability.
