Final answer:
Tantalum (Ta) is a transition metal with an atomic number of 73, recognized for its high melting point and resistance to corrosion, and widely used in electronics and medical technology.
Step-by-step explanation:
Tantalum (Ta) is a transition metal with the atomic number 73, known for its high melting point and resistance to corrosion. It is used in various applications including electronics and medical implants.
Tantalum is found in the transition metals section of the periodic table, positioned between hafnium (Hf) and tungsten (W). With an atomic number of 73, tantalum's electronic configuration is [Xe]4f¹⁴5d³⁴6s². This configuration explains many of its chemical properties, such as its high ductility, conductivity, and affinity for forming compounds with nonmetals.
Tantalum's high melting point of 3017°C and excellent corrosion resistance make it valuable in high-temperature environments. The element is relatively rare and is mainly obtained from tantalite minerals. It is also notable for its use in the manufacture of electronic components like capacitors and high-power resistors, where its stability and capacitance are prized. Moreover, tantalum is biocompatible, leading to its use in medical devices such as surgical implants and instruments.
