Question

search the table use the periodic table to answer the following questions. it may also be helpful to reference the periodic table of the elements, in pictures and royal society of chemistry. question 1 (3 points) which element in group 5 is used in some of the worlds fastest trains? a vanadium (v) b niobium (nb) c tantalum (ta) d dubnium (db)

Explanation:

Vanadium is used in steel - making for strength. Niobium is used in alloys for high - temperature applications. Tantalum has high melting point and is used in capacitors and also in some high - performance alloys relevant to fast - train technology. Dubnium is a synthetic and highly radioactive element with no practical industrial uses yet. By referring to the properties and applications of elements in group 5 and their relevance to fast - train technology, tantalum is the correct choice.

Answer:

C. Tantalum (Ta)
