Welcome back to another science lesson! Today, we're exploring the fascinating world of atomic structure. Atoms are the building blocks of matter, composed of a nucleus and electrons. The nucleus, located at the center, contains positively charged protons and neutral neutrons. Surrounding the nucleus are negatively charged electrons, which orbit in energy levels.Elements are defined by the atomic number, the number of protons in the nucleus. Isotopes are variations of elements with different numbers of neutrons, affecting the mass number. Ions form when atoms lose or gain electrons, resulting in a positive or negative charge.Understanding atomic structure helps us predict how different elements react and combine to form molecules. This knowledge is essential for exploring chemistry and physics.That wraps up our lesson! Keep asking questions and exploring the world around you. Thank you for joining me! Have a great day, and see you next time! Bye!
