Radium is a chemical element, not a compound.
Radium is a chemical element; a compound has a minimum of two chemical elements.
Radium is a chemical element, not a mixture.
Polonium and radium are radioactive chemical elements but they have not the same properties.
Radium is a divalent chemical element; the cation is Ra2+.
Radium and zinc do not have a strong attraction for each other, so they do not readily combine to form a compound. It is unlikely for these two elements to form a stable chemical bond due to differences in their chemical properties.
Radium is a natural chemical element, solid, alkaline earth metal.
Radium is a chemical element Polonium is a chemical element Both were discovered by Marie Curie
Radium is a chemical metal element. There are 88 electrons in a single atom.
Exposure to radium poses a hazard due to its radioactive properties. It can emit harmful radiation, leading to potential health risks such as an increased likelihood of developing cancer and other radiation-related illnesses. It is essential to limit exposure to radium and follow safety protocols when working with this substance.
In mathematics, the term "radium" is not commonly used. Radium is a chemical element with the symbol Ra on the periodic table. It is a radioactive element with atomic number 88.
Ra is the chemical symbol for Radium - a highly-radioactive element.
