Assertion: rutherfordium's property | /r/HasProperty | measured
Facets:
Source sentences:
text: Very few properties of rutherfordium or its compounds have been measured; this is due to its extremely limited and expensive production and the fact that rutherfordium (and its parents) decays very quickly.
text: A few singular chemistry-related properties have been measured, but properties of rutherfordium metal remain unknown and only predictions are available.
