explain structure of an atom

An atom is the smallest unit of matter that makes up everything in the universe. It is made up of three main parts: protons, neutrons, and electrons. Protons are positively charged particles, like the north end of a magnet. They are found at the center of the atom, known as the nucleus. Neutrons are uncharged particles and are also found in the nucleus. They are like the north and south ends of a magnet that are stuck together. Electrons are negatively charged particles and are found in a cloud-like pattern outside of the nucleus. They are like the south end of a magnet that is attracted to the north end. Analogies can help you understand the structure of an atom better. Think of the nucleus of an atom as a basketball and the electrons as the people surrounding it. The basketball is the nucleus and the people are the electrons. The basketball is the center of the atom and the people are surrounding it in a cloud-like pattern. Fun Fact: On average, there are more than 100,000,000,000,000,000,000,000,000 atoms in a single cup of water!
