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

∙ 12y agoNaturally occurring Europium has two isotopes. Isotopes are versions of an element with varying numbers of neutrons, therefore different masses. The two isotopes of natural Europium are 151Eu and 153Eu. These isotopes have 88 and 90 neutrons, respectively.
The number of neutrons in a Europium atom is found by subtracting 63 (the number of protons in Europium) from the superscripted number in the isotope notation.
151 - 63 = 88
153 - 63 = 90
Another isotope of Europium - 155Eu - is a fission product and does not occur naturally on Earth. Fission products are fragments left over after atomic nucleus fissions. This isotope is radioactive. The number of neutrons is found the same way as above: 155 - 63 = 92.
There are many other isotopes for Europium, although the ones discussed above are the most common. Use the process above to find the number of neutrons, depending on the atomic mass number given in the isotope notation.
Given : xEu X - 63 = # of neutrons

How many neutrons does an mg2 ion have?
It has 12 neutrons.
How many neutrons are found in argon?
There are 18, 20 or 22 neutrons.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.

How many protons electrons and neutrons are in europium?
63 protons and 89 neutrons
What is the mass number of europium?
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.
What is europium used for?
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.
How many protons does Europium have?
63.
How many neutrons are present in an atom that has an atomic number of 62 and a mass number of 151?
The atomic number refers to the number of protons in the nucleus. This is what dictates the atom's chemical properties. One proton, hydrogen. Two protons, helium, and so on. The mass number is the sum of protons and neutrons combined. Therefore, the number of neutrons in an atom of samarium (62 Sm 151) is the difference: 89 Samarium 151 is not stable, incidentally. It has a half life of 90 years, decaying by beta particle emission. What happens (essentially) is that one of those neutrons splits into a proton/electron pair. The electron is ejected from the nucleus. The atomic number goes up by one, but the mass remains the same. 62 Sm 151 transmutes into 63 Eu 151 (europium), which is a stable rare earth element.
How many protons does europium-151 have?
63
How can you use europium in a sentence?
