Europium is one of the lanthanides... that stretched out group on the bottom of most periodic tables. It's atomic number 63, so that gives it 63 protons and 63 electrons when it's in a neutral state. It has a number of different isotopes: the most stable isotope has 90 neutrons, followed by one with 88... there are 35 (!) other isotopes that have been produced that are radioactive... I'll spare us both by not listing them all. The electron configuration is the same as Xenon, plus 4f7 6s2.

Hope that helps!

It's got an atomic number of 63, and it is in the Lanthanide series.
It's Atomic weight is 151.96, so it has an average of 89 neutrons or so in its different isotopes. It's usually gonna have 63 electrons. 2 in the first shell (2 in the s orbital), 8 in the second shell (2 in the s orbital, and 6 in the p orbital), 18 in the third shell (2 in the s orbital, 6 in the p orbital, 10 in the d orbital), 32 in the fourth shell (2 in the s orbital, 6 in the p orbital, 10 in the d orbital, 14 in the f orbital), and 3 in the fifth shell (2 in the s orbital, and 1 in the p orbital).

I don't have any opium. Just beer, tequila, and wine.
