@builtnotbought92: ​We built a pocket-sized spot welder and emergency fire starter using two AA batteries, two metal screws, and a piece of copper wire. ​We did it by connecting the batteries in parallel so touching the screw tips creates an electric arc powerful enough to weld metal blades or ignite a cotton pad. #DIY #Tips #lifehacks #idea

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 isotopes. The mass number of an atom is the total count of both protons and neutrons combined, as electrons have almost no mass. The structure of the periodic table also reveals how atoms will interact with one another to form chemical bonds. It is organized into horizontal rows called periods and vertical columns called groups, which group elements with similar chemical properties together. Elements in the same group have the same number of valence electrons, which are the electrons in the outermost shell of the atom. Because atoms naturally strive to have a full outer shell of electrons to achieve stability, elements in the same column react in highly predictable ways, either sharing, gaining, or losing electrons to bond with other atoms.
