SPREAD THE SCIENCE:
Atoms are the fundamental building blocks of all matter in the universe, composed of three primary subatomic particles: protons, neutrons, and electrons. Protons carry a positive electrical charge and neutrons carry no charge, binding tightly together at the center of the atom to form a dense core called the nucleus. Surrounding this nucleus is a cloud of rapidly moving electrons, which carry a negative electrical charge and are attracted to the positive nucleus. In a neutral atom, the number of protons exactly equals the number of electrons, balancing the overall charge. The identity and behavior of an atom are determined by these subatomic particles, which is how the periodic table of elements is organized. Elements are arranged on the periodic table in order of increasing atomic number, which is the exact number of protons found in an element's nucleus. For example, hydrogen has one proton, while helium has two. While the number of protons defines the element, the number of neutrons can vary, creating different variations of the same element known as isotop
