What is the core at the center of every atom known as?

The core at the center of every atom is known as the nucleus. This is a central part of an atom where the majority of its mass is concentrated. The nucleus is composed of protons and neutrons, which are subatomic particles. Protons carry a positive charge, while neutrons are neutral. Together, these particles make up the atomic mass and play a crucial role in determining the chemical properties of the element.

The nucleus is surrounded by an electron cloud, where electrons, which are negatively charged particles, orbit the nucleus. This arrangement is fundamental to the structure of matter and influences how atoms interact with one another in chemical reactions. The dynamics of electrons within this cloud, alongside the nucleus, provide insights into the behavior of elements and their compounds.
