Mell Where is curium naturally found?
Source: Curium does not exist in nature. It is a synthetic element and it is produced in nuclear reactors by bombarding plutonium with neutrons. Isotopes: Curium has 15 isotopes whose half-lives are known, with mass numbers 238 to 252. Curium has no naturally occurring isotopes.

What compounds does curium make?
Scientists have produced several curium compounds. They include: curium dioxide (CmO2), curium trioxide (Cm2O3), curium bromide (CmBr3), curium chloride (CmCl3), curium chloride (CmCl3), curium tetrafluoride (CmF4) and curium iodide (CmI3).
What does curium feel like?
Curium is a hard, brittle, silvery metal that tarnishes slowly in dry air at room temperature. Curium is very radioactive, more electropositive than Aluminum, chenically reactive. A few compounds of curium are known, as the fluorides.
Does curium glow in dark?
Curium is the most radioactive element that can be isolated. It is so intensely radioactive that it boils water, making its chemistry difficult to study. It also glows in the dark (see right). Curium was first intentionally synthesised in 1944 by a team of chemists led by Glenn Seaborg.

What is ununoctium used for?
Uses of Ununoctium Element – There is no use of Ununoctium apart from basic science research. Ununoctium is harmful due to its radioactivity .
What does curium look like?
Curium is a hard, dense radioactive silvery-white metal. It tarnishes slowly in dry air at room temperature. Most compounds of trivalent curium are slightly yellow in color. Curium is highly radioactive and it glows red in the dark.
What does curium react with?
Curium readily reacts with oxygen forming mostly Cm 2O 3 and CmO 2 oxides, but the divalent oxide CmO is also known. Black CmO 2 can be obtained by burning curium oxalate (Cm 2(C 2O 4) 3), nitrate (Cm(NO 3) 3) or hydroxide in pure oxygen.
What are the physical properties of curium?
The physical properties of curium include a boiling point of 1,340°C (2,444°F), and a melting point of 3,110°C (5,630°F).
