Samarium
Because the atomic number is 62, the element Samarium has 62 electrons and 62 protons. Since the number of neutrons is calculated by subtracting the atomic number from the atomic mass, and Samarium's atomic mass is 150, it has 88 neutrons.
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
The atoms of the element samarium (atomic number 62) have the electron configuration [Xe] 4f6 6s2
Atomic number = Number of protons
The atomic number is the number of protons in an atom of an element.
Because the atomic number is 62, the element Samarium has 62 electrons and 62 protons. Since the number of neutrons is calculated by subtracting the atomic number from the atomic mass, and Samarium's atomic mass is 150, it has 88 neutrons.
Samarium, with the chemical symbol Sm, is the chemical element with the atomic number 62.
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
The element with 46 electrons and 62 neutrons is Palladium (Pd), which has an atomic number of 46 and an atomic mass of approximately 108. Total number of protons + neutrons = atomic mass.
The atoms of the element samarium (atomic number 62) have the electron configuration [Xe] 4f6 6s2
