Period and Group of Tantalum
Periodic Table of Elements
The periodic table of elements is a tabular arrangement of chemical elements based on the periodic trends in their properties. The elements are arranged in rows and columns according to their atomic number, electron configuration, and chemical properties.
Tantalum (Ta)
Tantalum is a chemical element with the symbol Ta and atomic number 73. It is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Tantalum is used in the production of capacitors, surgical implants, and nuclear reactors.
Period Number of Tantalum
The period number of an element in the periodic table is the number of electron shells it has. Tantalum has an atomic number of 73, which means it has 73 electrons arranged in different shells. The period number of an element is equal to the number of shells it has. Therefore, the period number of tantalum is 6.
Group Number of Tantalum
The group number of an element in the periodic table is the number of valence electrons it has. Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding. Tantalum belongs to group 5 of the periodic table because it has 5 valence electrons. Therefore, the group number of tantalum is 5.
Conclusion
The correct answer is option C, which states that the period number and group number of tantalum are 6 and 5, respectively.
