167.26 amu
Erbium
The inner transition metal with an atomic mass of approximately 167.26 is Erbium (symbol: Er, atomic number: 68).
The formula is Atomic Mass (rounded to the nearest whole number) minus the Atomic Number. This works because Protons and Neutrons have virtually the same mass, and electrons virtually none. As well as the Atomic Number being equal to the amount of Protons. Essentially: Protons + Neutrons - Protons = Neutrons. Basic Prealgebra. So to find the amount of Neutrons in Erbium: Erbium's Atomic Mass rounded (167) - Erbium's Atomic Number (68) = approx. 99 Neutrons
Erbium, with the chemical symbol Er, is the chemical element with the atomic number 68.
It is Erbium. Atomic number = 68, Rare Earth(Lanthanide)

It is Erbium. Atomic number = 68, Rare Earth(Lanthanide)
Erbium (atomic number 68). It is an example of lanthanide.
Er on the periodic table stands for erbium. Erbium is a lanthanide element with the atomic number 68. It is a silvery-white metal that is commonly used in optical amplifiers and as a component in nuclear reactors.
The element with atomic number 67 is Holmium (Ho). Holmium is a Lanthanide in Group 6 of the Periodic Table. Holmium has 67 electrons in 6 shells with 2 electrons in the outer shell.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
