How many electrons surround the nucleus of an atom of curium?
The nucleus consists of 96 protons (red) and 152 neutrons (blue). 96 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). Curium, named after the Curies and first synthesised in 1944, is an actinide and transuranic element in period 7, and the f-block of the periodic table.

Is Curium an element?
Curium/Atomic number
curium (Cm), synthetic chemical element of the actinoid series of the periodic table, atomic number 96. Unknown in nature, curium (as the isotope curium-242) was discovered (summer 1944) at the University of Chicago by American chemists Glenn T. Seaborg, Ralph A.
How is an atom of curium 242 different from an atom of curium 244?
The key difference between curium 242 and curium 244 is that curium 242 has 146 neutrons in its atomic nucleus whereas curium 244 has 148 neutrons in its atomic nucleus. It has a number of isotopes, which have the same atomic number but different mass numbers.

Name:Curium Symbol:Cm Atomic Number:96 Atomic Mass:(247.0) amu Melting Point:1340.0 °C (1613.15 K, 2444.0 °F) Boiling Point:Unknown Number of Protons/Electrons:96 Number of Neutrons:151 Classification:Rare Earth Crystal Structure:Unknown Density @ 293 K:13.511 g/cm3 Color:Unknown Atomic Structure Number of Energy Levels:7
What kind of structure does curium have at room temperature?
At pressures above 23 GPa, at room temperature, α-Cm transforms into β-Cm, which has a face-centered cubic symmetry, space group Fm 3 m and the lattice constant a = 493 pm. Upon further compression to 43 GPa, curium transforms to an orthorhombic γ-Cm structure similar to that of α-uranium, with no further transitions observed up to 52 GPa.

How did the element curium get its name?
Curium is named in honour of Pierre and Marie Curie, who pioneered the study of radioactivity in the final days of the 19th century. Nineteen radioisotopes of curium are known to exist, the first of which, 242Cu was isolated in the hydroxide form in 1947 and in its elemental form in 1951.
