Questions & Answers

Q: How are super heavy elements like 114 and 116 created?

Super heavy elements are made by accelerating calcium ions and allowing them to collide with heavier elements like plutonium, leading to the fusion of atoms and the formation of these elements.

Q: How was the existence of elements 114 and 116 proved?

Scientists collected data on the decays of these elements, observing the emission of gamma rays as the atoms decayed. The detection of specific gamma rays provided strong evidence for the existence of these elements.

Q: What is the significance of the IUPAC's decision?

The IUPAC's decision to include elements 114 and 116 in the periodic table signifies that the evidence for their existence is now considered beyond reasonable doubt by the scientific community.

Q: What will happen to elements 114 and 116 now?

Elements 114 and 116 will receive names, most likely based on the scientists or individuals who made significant contributions to their discovery. Nationalistic names will be avoided due to the international collaboration involved.

Summary & Key Takeaways

• The International Union of Chemistry (IUPAC) has announced that elements 114 and 116 have met the criteria for inclusion in the periodic table.

• These super heavy elements are created by combining heavy elements like plutonium with calcium ions at high speeds.

• Scientists from Russia and the United States have provided data supporting the existence of these elements, and the evidence has been examined and accepted by the IUPAC.
