: Particles with no charge, also found in the nucleus. They provide stability and contribute to the atom's mass.
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. They are incredibly small, typically around 100 picometers across. Atomic Structure Atoms are made of three main subatomic particles: Licensed by Google : Particles with no charge, also found in the nucleus
: Negatively charged particles that orbit the nucleus in specific regions called shells or orbitals. They are much smaller than protons and neutrons. Key Characteristics Every solid, liquid, gas, and plasma is composed
: Positively charged particles located in the center of the atom (the nucleus). The number of protons determines the identity of the element. They are much smaller than protons and neutrons
: This is the count of protons in the nucleus. For example, Hydrogen has 1 proton, while Gold has 79.
