The atomic number of hafnium (Hf) is 72.
The atomic weight of Hf is 178.49 grams per mole.
See the Web Links to the left of this answer for a periodic table with more information about this element!
The atomic number of hafnium is 72. So there is 72 protons.
Position of hafnium in the periodic table: group 4, period 6, atomic number 72.
The atomic mass of hafnium is approximately 178.49 atomic mass units.
Hafnium (Hf) is a natural chemical element.
Hafnium is a natural chemical element, rare, solid transition metal, atomic number 72, group 4 and period 6 in the table of elements.
* Number of Electrons: 72 * Number of Neutrons:106 * Number of Protons: 72 * Number of Electrons: 72 * Number of Neutrons: 106 * Number of Protons: 72
the atomic number of hafnium is 72, protons? 72, neutrons? 106, electrons? 72
The atomic number of hafnium is 72. So there is 72 protons.
Position of hafnium in the periodic table: group 4, period 6, atomic number 72.
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
The atomic mass of hafnium is approximately 178.49 atomic mass units.
The superscript is the atomic mass number, which is the sum of protons and neutrons. The subscript is the atomic number, which is the number of protons. For a hafnium nuclide with 107 neutrons, the superscript would be 180 (107 neutrons + 73 protons) and the subscript would be 73.
Hafnium (Hf) is a natural chemical element.
Hafnium is a natural chemical element, rare, solid transition metal, atomic number 72, group 4 and period 6 in the table of elements.
Hf is the symbol on the periodic table for the element Hafnium, it has an atomic number of 72.
The element with the word "hen" in its name is hafnium. Hafnium is a metallic chemical element with symbol Hf and atomic number 72.
the answer is 109... im not positive that im right but if i am right heres what you do... subtract the atomic mass from the atomic number(number of protons.) :p
