It is estimated that the chemical properties of dubnium are similar to these of tantalum.
Tantalum is a dense, silvery metal that is highly resistant to corrosion and has a high melting point. It is often found in the form of greyish powder or dark metal in its natural state. Tantalum is used in various industrial applications due to its unique properties.
Tantalum can exist in two crystalline phases: alpha and beta. The common phase is alpha but beta tantalum can be found bt magnetron spluttering or chemical vapour deposition. It converts to the alpha phase is heated to around 1000 K.Beta tantalum crystals have tetragonal symmetry.
In 1800, the element sulfur was thought to be identical to the element selenium, which is directly above it in the periodic table. This was due to their similar chemical properties and physical appearances. It wasn't until the 19th century that their distinct differences were recognized through further scientific research and experimentation.

Tantalum
Yes, tantalum is considered a rare metal. It is relatively scarce in the Earth's crust and is often found in conjunction with other metals such as niobium. Its rarity, along with its unique properties, makes tantalum a valuable material for various high-tech applications.

Tantalum is a metal and does not have a particular natural odor.
