Properties of Chromium
- Chromium belongs to 6th group, 4th 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
