The electronic configuration of chromium is__________

Answer:

The electronic configuration of chromium is 1s²2s²2p⁶3s²3p⁶3d⁵4s¹.

Chromium

Chromium is a chemical element with the atomic number of 24 and represented by the symbol Cr in the Periodic Table. It’s a hard, lustrous silver-grey metal with a lustrous texture. It’s an element with a high melting point.

Properties of Chromium

• Chromium belongs to 6^th group, 4^th period and d-block element
• Melting and boiling point of chromium is 1907 °C and 2672 °C respectively.
• The expected electron configuration for Chromium will be 1s²2s²2p⁶3s²3p⁴4s²3d⁹
• Half-filled and fully filled subshell have got extra stability. Therefore, one of the 4s² electrons jumps to the 3d⁵ so that it is half-filled. This shows the configuration of the chromium atom 1s²2s²2p⁶3s²3p⁴ 3d⁵ 4s¹
