63.
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.
63
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! ^.^
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.

Iodine (I) has 53 electrons; the number of electrons is identical to number of protons and the atomic number.
89

The element europium is named after the continent Europe.
Europium, number 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.
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).
