Terbium has 65 electrons
Electrically neutral terbium's atomic number is 65. Therefore, it has 65 protons and 65 electrons. Terbium's only stable isotope is 159Tb, and thus it has 159 - 65 = 94 neutrons. That brings the total amount of subatomic particles in a terbium atom to 65 + 65 + 94 = 224.
Terbium (Tb) is part of the Lanthanide series of Inner Transition Metals. A good way to determine the number of valence electrons which Terbium holds under standard conditions is to write out the electron configuration.In the Abbreviated form: [Xe] 4f^9 6s^2Therefore, Tb has 11 valence electrons and 54 core electrons
terbium is synthetic i believe
Terbium is actually pretty soft, but it resists impacts well. My teacher hit a small piece with a hammer and it didn't break, but it did spark. A knife can scratch terbium easily. So can the coating on a neodymium magnet.
