1. Electron Configuration:
* Sodium (Na) has an atomic number of 11, meaning it has 11 protons and 11 electrons.
* The electron configuration of sodium is 1s² 2s² 2p⁶ 3s¹.
2. Orbitals:
* 1st Orbit (n=1): Contains the 1s orbital, which holds a maximum of 2 electrons.
* 2nd Orbit (n=2): Contains the 2s and 2p orbitals.
* The 2s orbital holds 2 electrons.
* The 2p orbitals hold a maximum of 6 electrons.
* 3rd Orbit (n=3): Contains the 3s orbital, which holds a maximum of 2 electrons.
3. Electron Distribution:
* 1st Orbit: 2 electrons (1s²)
* 2nd Orbit: 8 electrons (2s² 2p⁶)
* 3rd Orbit: 1 electron (3s¹)
Therefore, sodium has:
* 2 electrons in the first orbit.
* 8 electrons in the second orbit.
* 1 electron in the third orbit.
