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.

The atoms of the element samarium (atomic number 62) have the electron configuration [Xe] 4f6 6s2
To determine the number of atoms in 56.279 g of samarium, you need to first calculate the number of moles using the molar mass of samarium (150.36 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
62 and its a lanthanide not an actinide as its often confused
The number of neutrons in any element is equal to mass number - atomic number. So,number of neutrons in cobalt is = 58 - 27 = 32. therefore, number of neutrons in cobalt is 32.
There is 88 neutrons
There are 88 neutrons in Samarium (Sm). This can be calculated quite easily: Neutrons=1amu Protons=1amu Since the atomic mass is equal to the sum of protons and neutrons, and the atomic number is the number or protons, you can simply subtract the mass from the atomic number to see how many neutrons are present. (Atomic Mas - Atomic Number = Number of neutrons) 150 - 62 = 88 (Note: The mass of Sm is slightly larger than 150 but for the purpose of time, mass is almost always rounded in calculations)
88
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.
Samarium, with the chemical symbol Sm, is the chemical element with the atomic number 62.
Samarium has six electron shells.
The noble gas notation for samarium is [Xe] 6s2 4f6.
This isotope does not occur in the environment and thus must be produced synthetically.

Samarium is a chemical element with the symbol Sm and atomic number 62. It is a silvery metal that is part of the lanthanide series of the periodic table. Samarium is commonly used in the production of powerful magnets and in nuclear reactors.
The atomic number (Z) is 62, indicating 62 protons in the nucleus. The mass number (A) is 151, which is the sum of protons and neutrons. Therefore, the number of neutrons present would be 151 (mass number) - 62 (protons) = 89 neutrons.
