Darmstadtium
Atomic number 110 means that every Darmstadtium nucleus contains 110 protons. That proton count is the element's identity: change it and you no longer have Darmstadtium.
Start with the nucleus
Atomic number 110 means that every Darmstadtium nucleus contains 110 protons. That proton count is the element's identity: change it and you no longer have Darmstadtium.
Darmstadtium (Ds) is chemical element 110. It belongs to the elements whose chemistry is still being explored, and its reference state at room temperature is not firmly established. Those basic facts are a useful starting point for its chemistry and applications.
In practice, it turns up most often in scientific research.
