Question

Which atom has the electron configuration: 1s22s22p63s23p64s23d104p65s24d2?

Answer 1

Answer:

zirconium has this electronic configuration.

Explanation:

the total no of electron is 40 in this aton hence this is its atomic no.

the metal with atomic no 40 is zirconium.

hope you understand it...

Answer 2

Answer:

Zirconium has this electronic configuration containing total 40 electrons .

Explanation:

Zirconium has this electronic configuration containing total 40 electrons .

• Chemical element zirconium has the atomic number 40 and the symbol Zr.
• Zirconium gets its name from the mineral of the same name.
• The name is related to the most significant zirconium source, Persian zargun (zircon; zar-gun, "gold-like" or "like gold").
• It is a strong, lustrous transition metal that closely resembles titanium and, to a lesser extent, hafnium.
• It is grey-white in colour. Zirconium is mostly employed as a refractory and an opacifier, while it is also used in tiny amounts as an alloying agent due to its excellent corrosion resistance.
• Numerous inorganic and organometallic compounds, including zirconium dioxide and zirconocene dichloride, are formed from zirconium. Four of the five isotopes that exist in nature are stable. Compounds made with zirconium play no recognised biological purpose.
