What is the electron configuration of a sulfur atom in the ground state

What is the electron configuration of a sulfur atom in the ground state ?
1) 2-8-4
2) 2-6
3) 2-4
4) 2-8-6

The Correct Answer and Explanation is :

he correct electron configuration of a sulfur atom in its ground state is option 4: 2-8-6.his notation indicates that sulfur has two electrons in its first energy level, eight in the second, and six in the third.
ulfur has an atomic number of 16, meaning it possesses 16 protons and, in a neutral atom, 16 electrons.hese electrons are arranged in energy levels or shells around the nucleus, following the principles of quantum mechanics.
he distribution of electrons among these shells adheres to the Pauli exclusion principle and Hund’s rule.he Pauli exclusion principle states that no two electrons can have the same set of quantum numbers, effectively limiting the number of electrons in each orbital.und’s rule indicates that electrons will occupy degenerate orbitals singly before pairing up, minimizing electron-electron repulsions within a subshell.
n sulfur’s case, the electron configuration can be detailed as follows:

• First energy level (n=1): his level has one s orbital (1s), which can hold up to two electrons. Sulfur fills this orbital completely: 1s².
• Second energy level (n=2): his level comprises one s orbital (2s) and three p orbitals (2p). The 2s orbital holds two electrons: 2s². The three 2p orbitals can collectively accommodate six electrons, and sulfur fills them all: 2p⁶. Thus, the second energy level contains a total of eight electrons.
• Third energy level (n=3): his level includes one s orbital (3s) and three p orbitals (3p). The 3s orbital is fully occupied with two electrons: 3s². The 3p orbitals can hold up to six electrons, but sulfur has only four electrons remaining, so it partially fills these orbitals: 3p⁴.
  ombining these, the full electron configuration of sulfur is: 1s² 2s² 2p⁶ 3s² 3p⁴.his configuration shows that sulfur has two electrons in the first shell, eight in the second, and six in the third, corresponding to the 2-8-6 notation.
  nderstanding sulfur’s electron configuration is crucial because it explains the element’s chemical properties and reactivity.he six valence electrons (those in the outermost shell) make sulfur prone to gaining or sharing two electrons to achieve a stable octet configuration, which is a key factor in its ability to form compounds such as hydrogen sulfide (H₂S) and sulfur dioxide (SO₂).
  n summary, the 2-8-6 electron configuration of sulfur reflects the arrangement of its 16 electrons across the first three energy levels, aligning with the principles of quantum mechanics and providing insight into its chemical behavior.
