The pursuit of discovering new elements has been a significant scientific endeavor for centuries, and recent advancements have enabled scientists to create superheavy elements with up to 118 protons. These elements are generally unstable due to the electromagnetic repulsion between protons overpowering the nuclear force that holds the nucleus together. However, there is a predicted “island of stability” where elements with around 164 protons could exist with a longer half-life or even be stable.
Research teams, including physicists, are investigating the properties of these superheavy elements, such as mass density, to determine where they might be found. Using a model that depicts atoms as charged clouds, they have calculated that stable elements in the island of stability could have densities ranging from 36 to 68 g/cm3, potentially 40% higher. These calculations are crucial for understanding where to search for such elements, including beyond Earth.
It is hypothesized that asteroids, which may have brought heavy metals to Earth, could also carry superheavy elements. Due to their high density, these elements would likely sink below Earth’s surface, but they could still be present in asteroids. The concept of Compact Ultradense Objects (CUDOs) has been introduced to describe these dense celestial bodies, which might contain superheavy elements at their cores.
Future space missions and projects, such as the European Space Agency’s Gaia mission and NASA’s Psyche mission, aim to map the sky in detail and analyze asteroid samples. These initiatives could reveal the presence of superheavy elements by identifying asteroids with unusually high densities and studying the material collected from their surfaces. Understanding these elements and their origins could provide insights into the formation of the solar system and the nature of the universe.
Key Takeaways:
- Scientists have been able to create new, superheavy elements by fusing atomic nuclei, with some elements possibly being stable around 164 protons in an “island of stability.”
- Researchers are investigating the possibility of superheavy elements existing in the cores of dense asteroids, which may have been delivered to the solar system through extreme astronomical events.
- Space missions like NASA’s Psyche are targeting metal-rich asteroids to collect samples that could contain superheavy elements, aiding in the understanding of the universe’s composition.
“Many scientists believe that gold and other heavy metals were deposited on Earth’s surface after asteroids collided with the planet. The same thing could have happened with these superheavy elements, but super mass dense heavy elements sink into ground and are eliminated from near the Earth’s surface by the subduction of tectonic plates.”
