Webnuclear fusion, process by which nuclear reactions between light elements form heavier elements (up to iron). In cases where the interacting nuclei belong to elements with low atomic numbers (e.g., hydrogen [atomic number 1] or its isotopes deuterium and tritium), substantial amounts of energy are released. The vast energy potential of nuclear fusion … WebAtoms can form strong bonds with each other, making molecules . A pure substance made from only one type of atom is called an element. Elements are listed on the periodic …
