58 electrons because the number of electrons is the same number of protons [] [] () (---------------------)
Cerium (Ce) has 58 protons. It is number 58 on the periodic table.
Cerium's atomic number is 58. Thus, it always has 58 protons. Its most common isotope is 140Ce, which has 140 - 58 = 82 neutrons.
Cerium has 82 neutrons. :)) your welcome.

Cerium is soft
Cerium is an inner transition metal.
Cerium is a solid at room temperature
A soft, ductile, and silvery-white metal that tarnishes when exposed to air. It is the second element in the lanthanide series, and while it often shows the oxidation state of +3 characteristic of the series, it also has a stable +4 state that does not oxidize water. Cerium dioxide is employed in the optics industry for the fine polishing of glass.
Cerium generally forms ionic compounds.
There are 82 neutrons in Cerium (Ce).
Cerium's atomic number is 58. Thus, to be electrically neutral, cerium must have 58 protons and 58 electrons. 140Ce is its most abundant isotope with 140 - 58 = 82 neutrons.
Cerium was discovered in 1803 Cerium--- Ce atomic number--- 58 atomic mass--- 140.116 # of protons--=58 # of neutrons--- 82 # of electrons---58
