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.
Terbium is a relatively soft metal, with a Mohs hardness of about 1.2 - 1.5. It can be easily cut with a knife and has a low hardness compared to many other metals.
Terbium has 65 electrons.
Terbium has a group number of 3.
Terbium is a natural element found in the Earth's crust. It is a lanthanide metal that is primarily extracted from minerals containing rare earth elements.
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.
As of now, the cost of terbium is approximately $400-500 per kilogram. However, prices can vary based on market demand and supply.

Terbium is a natural element found in the Earth's crust. It is a lanthanide metal that is primarily extracted from minerals containing rare earth elements.
Terbium is flammable and burns with a yellowish flame.
The symbol for the element Terbium is Tb
The atomic mass of terbium is 158.92
Green trichromatic
The atomic weight of terbium is 158.93 amu.
Terbium is in the period 6 and is a member of lanthanoids family.
Scandium is element 21, and terbium is element 65.
Berkelium has the electronegativity 1,3 in the L. Pauling scale; terbium has an electronegativity of 1,1. Berkelium is more reactive than terbium.
The element terbium was discovered in 1843 by Carl Gustaf Mosander, a chemist living in Sweden. Terbium has the symbol Tb and its atomic number is 65.
Terbium, with the chemical symbol Tb, is the chemical element with the atomic number 65.
