What is an atom?

An atom is the basic unit of matter that consists of a nucleus made up of protons and neutrons, surrounded by a cloud of electrons. It is the smallest particle of an element that retains the chemical properties of that element. Atoms are incredibly small, with a diameter of about 1 to 2 angstroms (1 angstrom is equal to 0.1 nanometers). They are the building blocks of everything around us, including all living and non-living things.

An atom is the basic unit of matter and the smallest unit of a chemical element. It consists of a nucleus, which contains positively charged protons and neutrally charged neutrons, surrounded by negatively charged electrons. The nucleus makes up the majority of the atom's mass, while the electrons occupy the space around it. Atoms are electrically neutral, meaning that the number of protons and electrons is equal, resulting in no overall charge. It is the arrangement and interaction of atoms that determine the properties and behavior of matter.

An atom is the basic unit of matter that consists of a nucleus and electrons. The nucleus is composed of protons and neutrons, while the electrons revolve around the nucleus in specific energy levels.

To understand atoms better, you can consult reliable scientific sources such as textbooks, reputable websites, or educational videos. These resources can describe the structure of an atom in more detail, including the arrangement of subatomic particles and the forces that hold them together. Additionally, you may find interactive simulations or models that help visualize atomic structure, making it easier to grasp the concept.
