europium's atomic number is 63, it's mass (in amu's [Atomic Mass units]) is 152, rounded. the atomic number = the number of protons, so europium has 63 protons.
the number of protons = the number of electrons, so there are 63 electrons in a europium atom.
the mass= protons + neutrons, therefore neutrons = mass - protons.
this would be 152 - 63 = 89
there are 89 neutrons in a europium atom.
p+: 63
n: 89
e-: 63
hope i helped! ^.^
There are 18, 20 or 22 neutrons.
Hydrogen typically has 0 neutrons.
In-115 isotope has 66 neutrons
the average amount of neutrons in chlorine is 18, but there could be more or less with the different isotopes
Number of neutrons is 48 (mass number) minus 21 (proton number) = 27 (neutron number)
In europium, the number of protons is 63, electrons is also 63, and neutrons can vary based on the isotope of europium. The most common isotope, europium-153, has 90 neutrons.
89
Mass number is the number of protons and neutrons in the nucleus of an atom. And we might consider that the mass number of europium is 153 and call it good. Europium has an atomic number of 63, and there is only one stable isotope of it - europium-153. This isotope has the 63 protons and 90 neutrons. But there are other isotopes of europium, and their mass numbers range from 130 through 167 because europium has isotopes with neutron counts from 47 through 104. Use the link below for more information.
63.
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.

Because Europium is fairly difficult to obtain it has few practical uses. Europium is unique in the fact that it can absorb more neutrons per atom then any other element. Thus making Europium and its isotopes very valuable in control rods of nuclear reactors. Like many other transition metals Europium is used in producing certain alloys, including striker and lighter flints. It's also been used in the creation of infrared absorbing automotive glass. Europium's compound, Europium Oxide, is often used as a phosphor activator. Europium's other two roles are also involved with phosphors. Europium is used in the production of phosphors for the creation of small lasers. But perhaps what Europium is known best for is the production of the red phosphors that are found in all color television screens.
The element europium is named after the continent Europe.
Europium, number 63
Scandium is Sc and Europium is Eu.
The Latin name for europium is Europium (symbol: Eu), taken from the continent Europe where it was discovered. Its Greek name is Ευρώπιο (Efρωπιο).
Europium is a light pink color. Europium is used as the red phosphor in color television and lasers. Europium is used as a neutron absorber in nuclear research. The atomic weight of Europium is 151.96.
