ZR Speaker Lab was created in 1983.
The noble gas in the same period as Zr (Zirconium) is Kr (Krypton). Both Zr and Kr are in the fourth period of the periodic table.
Zirconium, a transition element with an atomic number of 40, has several isotopes, and each has a different mass number. Zr-88 (mass number 88), Zr-89 (mass number 89), Zr-90 (mass number 90), Zr-91 (mass number 91), Zr-92 (mass number 92), Zr-93 (mass number 93), Zr-94 (mass number 94) and Zr-96 (mass number 96).
The electron configuration of zirconium (Zr) is Kr 5s² 4d². When zirconium loses three electrons to form Zr³⁺, it typically loses the two 5s electrons first, followed by one 4d electron. Therefore, the electron configuration for Zr³⁺ is Kr 4d¹.
Zirconium (Zr) has the same noble gas electron configuration as Krypton (Kr). In its electron configuration, Zr has 36 electrons, which corresponds to the 36 electrons of Kr, representing the filled outer electron shells characteristic of noble gases.
