How many isotopes does curium have?
14
Curium has 14 known isotopes. They range in mass from 237 to 251. Though none are stable, 247Cm has a half-life of about 15,600,000 years.
What does curium bond with?
Named after Pierre and Marie Curie, curium is a silvery, radioactive metal. It is a chemically active metal, reacting with air, water and acids but not bases.

What element is the heaviest?
uranium
The heaviest naturally stable element is uranium, but over the years physicists have used accelerators to synthesize larger, heavier elements. In 2006, physicists in the United States and Russia created element 118.
What are the common isotopes?
Common stable isotopes include 2H/H, 18O/ 16O, and 13C/ 12C. These isotopes occur naturally in the environment, but their natural abundance differs with different environmental conditions.
What are three uses of curium?
Applications of Curium The isotopes of curium such as curium- 244 and curium 242 are used in power generation industries such as thermo-electric and thermionic converters. This metal is used in the X-ray spectrometer for the purpose of quantitative analysis In medical applications, it is used as power source. One gram of curium produces around 3 watts of thermal energy.
What do isotopes always have the same element?
Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes . Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
Do isotopes have the same atomic number?
All isotopes of an element have the same atomic number. What they differ in is their ‘mass number‘ (usually abbreviated ‘A‘), which denotes the total number of protons and neutrons in an atom’s core. In other words, isotopes are atoms of the same element — but some just weigh more.
