Atomic Nucleus
The atomic nucleus is the dense core at the center of an atom, composed of protons and neutrons, which are themselves made of quarks. Protons are positively charged, while neutrons are neutral, and together they determine the element and its mass. Nuclear structure refers to how these particles are arranged and interact. Nuclear fission is a process where the nucleus of a heavy atom splits into smaller nuclei, releasing a significant amount of energy; this is the principle behind nuclear power and atomic bombs. Understanding the nucleus is essential for nuclear chemistry, physics, and energy generation.

The atomic nucleus is the central part of an atom, composed of protons and neutrons. Protons are positively charged, while neutrons have no charge. Together, they make up most of the atom's mass. The nucleus is surrounded by a cloud of negatively charged electrons, which orbit around it. The arrangement and number of protons determine an element's identity and its chemical properties. The nucleus is held together by a strong nuclear force, overcoming the repulsion between the positively charged protons. Understanding the nucleus is essential to fields like chemistry, physics, and nuclear energy.
