What is the name of the element with Z=41? 6. What is the symbol of the element with Z=41 (use isotope symbol notation)? 7. What is the atomic weight of the element with Z=41?
The Correct Answer and Explanation is:
The element with atomic number (Z) = 41 is Niobium.
- Name of the Element (Z = 41):
The element with Z = 41 is Niobium. It was discovered by the English chemist Charles Hatchett in 1801. Niobium is a transition metal located in Group 5 of the periodic table. Its name is derived from Niobe, the daughter of the Greek mythological figure Tantalus, who was also associated with the element Tantalum. - Isotope Symbol Notation:
The symbol of niobium is Nb. In isotope notation, this would be written as Nb-93 (most stable isotope) or Nb-92, etc., depending on the isotope. The number following the symbol indicates the mass number, which is the sum of protons and neutrons in the nucleus. For example, niobium-93 is the most abundant isotope, with 41 protons and 52 neutrons. - Atomic Weight of Niobium:
The atomic weight (or atomic mass) of niobium is approximately 92.906 g/mol. The atomic weight represents the weighted average of all the naturally occurring isotopes of an element, accounting for their relative abundance. For niobium, the atomic weight primarily reflects the isotopes niobium-93 (the most abundant) and trace amounts of niobium-92. Niobium is a relatively stable element, and its isotopes are not radioactive under normal conditions.
Niobium is used in various applications, especially in high-strength steel alloys, superconducting magnets, and as an essential component of some jet engines due to its high melting point and excellent corrosion resistance.
