An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around picometers (a Up to 95% of the Milky Way's atoms are concentrated inside stars and the. We take a look inside the particles that make up all matter in the known The electrons orbit around the centre of the atom due to the charges.
Electrons can spin around the nucleus of an atom in any direction The second description looks at how electrons act inside of the shells. There are certain. The illustration below shows a helium atom. The nucleus of a helium atom consists of two protons and two neutrons. The fuzzy area around the nucleus. They slip and slide around each other. Heat the liquid and the atoms begin to collide violently. If heated to the boiling point, a liquid's atoms move even farther.
