Best Answer

The atomic number if curium (Cm) is 96 and its approximate Atomic Mass is (247).

The () denotes that the exact mass is not confirmed, as curium is radioactive and unstable. So it is not easy to calculate the exact mass of all its isotopes.

How many protons and neutron and electron and nucleus electron cloud are the in curium?

Curium has 96 protons. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; for the isotopic masses of curium read at the link below.


How many neutrons does the most naturally occurring isotope of curium have in its nucleus?

Curium is an artificial chemical element. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; and atomic mass is 247 so no of neutrons is 151.


How many neutron are in curium?

What happens when californium 251 decays into curium 247?

When californium-251 decays into curium-247, it undergoes alpha decay, releasing an alpha particle (helium nucleus) in the process. This results in the transformation of the nucleus to curium-247 with a simultaneous decrease in atomic number and mass number.
