Yes it is. Hafnium (symbol, Hf) is a transition metal, belong to group 4 and period 6
non metal
Hf is the symbol on the periodic table for the element Hafnium, it has an atomic number of 72.
Caesium is the most reactive.
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.
Sodium metal is an element.
Hf is the element hafnium. A dense gray metal. HF is the compound hydrogen fluoride, a toxic, acidic gas.

Hafnium
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.
Hf is the symbol on the periodic table for the element Hafnium, it has an atomic number of 72.
Well, this should be Xe6s24f145d2 which is element number 72 hafnium (Hf).
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.
