To determine the total number of electrons present in the kernel of Chromium-24 (Cr-24) for m = 0, we need to understand the electron configuration and the concept of the kernel.
Understanding Chromium-24
- Chromium (Cr) has an atomic number of 24, which means it has 24 electrons when neutral.
- The electron configuration of Chromium is:
- 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s¹
- The kernel refers to the inner electrons that are not involved in bonding or chemical reactions.
Kernel Electrons in Chromium
- The kernel consists of all electrons except for the outermost electrons.
- In the case of Chromium, the outermost electrons are in the 4s¹ and 3d⁵ orbitals.

Counting Kernel Electrons
- To find the kernel electrons, we will count the electrons in the filled inner shells:
- 1s²: 2 electrons
- 2s²: 2 electrons
- 2p⁶: 6 electrons
- 3s²: 2 electrons
- 3p⁶: 6 electrons
- Total kernel electrons = 2 + 2 + 6 + 2 + 6 = 18 electrons.
Conclusion
- For chromium-24, the total number of electrons present in the kernel is 18.
- The m = 0 quantum number indicates that we are considering the s orbital, but since we are calculating kernel electrons, it does not change the total count.
This gives a comprehensive understanding of the kernel electrons in Chromium-24!
