What is the atomic number of hafnium?
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!
Explain the different between Hf and HF?
Hf is the element hafnium. A dense gray metal. HF is the compound hydrogen fluoride, a toxic, acidic gas.
Is HF an element or a compound?
Capitalization matters in chemistry. Hf (uppercase H, lowercase f) is the element known as hafnium. HF (both letters uppercase) is the compound known as hydrogen fluoride.
What is the element with 73 protons?
The element with 72 electrons is Hafnium (Hf). Hafnium has an atomic weight of 72 and is a period 6, group 4 transition metal. It is the first element after the Lanthanides. Hafnium has 72 electrons in 6 shells with 2 electrons in the outer shell.
What is Hf on the periodic table?
Hf is the symbol on the periodic table for the element Hafnium, it has an atomic number of 72.
What element is Xe5d2?

What element has more that 50 protons but less than 75 protons?
The number of protons in the nucleus of any element is its atomic number. The atomic number is what defines an element. In other words, if an atom had 5 protons, it would be one element, but if it had 6 protons, it would be another element. You can find the atomic number of any element on a periodic table of the elements. The elements with greater than fifty protons and less than 75 protons are: 51: Sb(Antimony) 52: Te(Tellurium) 53: I(Iodine) 54: Xe(Xenon) 55: Cs(Cesium) 56: Ba(Barium) 57: La(Lanthanum) 58: Ce(Cerium) 59: Pr(Praseodymium) 60: Nd(Neodymium) 61: Pm(Promethium) 62: Sm(Samarium) 63: Eu(Europium) 64: Gd(Gadolinium) 65: Tb(Terbium) 66: Dy(Dysprosium) 67: Ho(Holmium) 68: Er(Erbium) 69: Tm(Thulium) 70: Yb(Ytterbium) 71: Lu(Lutetium) 72: Hf(Hafnium) 73: Ta(Tantalum) 74: W(Tungsten) If you want elements with atomic number 50 and 75 as well: 50: Sn(Tin) 75: Re(Rhenium I hope this helps.
Is the hf element a solid liquid or a gas?
HF [note correct capitalization] is not an element but a compound, since it contains two kinds of atoms. It is a gas at standard temperature and pressure.
Is element Hf a Metal?
Yes it is. Hafnium (symbol, Hf) is a transition metal, belong to group 4 and period 6
