Darmstadtium (Ds) is a synthetic, radioactive element with atomic number 110. The bracketed representative mass number is the mass number of a radioactive isotope, not a standard atomic weight. Its isotopes decay rapidly, and available measurements are limited to very small numbers of atoms; bulk physical properties such as density, melting point, and boiling point are unknown.
Research and occurrence
Darmstadtium is a synthetic, radioactive element that has been created only atom by atom in accelerator experiments. Its chemical and physical properties are not established from bulk samples; some values are theoretical predictions. It is studied in fundamental research and has no known commercial or water-treatment application.
Health and environmental context
Darmstadtium does not occur naturally in measurable quantities and is not an environmental contaminant encountered in ordinary water or process-water treatment. It is handled only in specialised, controlled research settings.
