How many protons does cerium have?
58
Cerium/Atomic number
Cerium is a chemical element with an atomic number of 58. This means that the nucleus of cerium has 58 protons in it. The atomic mass of cerium is 140.12. The chemical symbol of cerium is Ce and it is a member of the lanthanide group.
Does cerium have 2 valence electrons?
Its 58 electrons are arranged in the configuration [Xe]4f15d16s2, of which the four outer electrons are valence electrons. This gives rise to dual valence states. For example, a volume change of about 10\% occurs when cerium is subjected to high pressures or low temperatures.

How many neutrons does CS have?
The only stable caesium isotope is 133Cs, with 78 neutrons.
What is an example of a valence electron?
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
Can there be 9 valence electrons?
Re: Having more than 8 valence electrons Hey there! Some molecules can accommodate more than 8 valence electrons because they have expanded valence shells. These molecules are from periods 3 or higher because starting from n=3, atoms have d-orbitals that can accommodate for more that 9 valence electrons.
How many protons and electrons does cerium have?
Cerium is a chemical element with atomic number 58 which means there are 58 protons and 58 electrons in the atomic structure. The chemical symbol for Cerium is Ce. Neutron Number and Mass Number of Cerium Mass numbers of typical isotopes of Cerium are 140, 142.
How many protons electrons and electrons are in CE 58?
Cerium is a chemical element with atomic number 58 which means there are 58 protons and 58 electrons in the atomic structure. The chemical symbol for Cerium is Ce. Mass numbers of typical isotopes of Cerium are 140, 142.
What is the oxidation number of valence electrons in ceria?
Furthermore, each cerium atom in ceria does not lose all four of its valence electrons, but retains a partial hold on the last one, resulting in an oxidation state between +3 and +4.
What is the difference between caesium and cerium?
Not to be confused with caesium or curium. Cerium is a chemical element with the symbol Ce and atomic number 58. Cerium is a soft, ductile, and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a steel kitchen knife.
