The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct electron configuration of a ground-state titanium (Ti) atom is:<\/p>\n\n\n\n

Ar\\text{Ar}Ar 4s\u00b2 3d\u00b2<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Titanium (Ti) has an atomic number of 22<\/strong>, which means it has 22 electrons<\/strong> in its neutral ground state.<\/p>\n\n\n\n

To write its electron configuration, we fill the orbitals in the order of increasing energy using the Aufbau principle<\/strong>, which follows this general order:<\/p>\n\n\n\n

1s \u2192 2s \u2192 2p \u2192 3s \u2192 3p \u2192 4s \u2192 3d \u2192 4p, and so on.<\/p>\n\n\n\n

Filling the first 18 electrons gives us the electron configuration of Argon (Ar)<\/strong>:<\/p>\n\n\n\n

Ar\\text{Ar}Ar = 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076<\/strong>
Total = 18 electrons.<\/p>\n\n\n\n

After Argon, the next electrons go into:<\/p>\n\n\n\n

    \n
  • 4s orbital<\/strong>: 2 electrons \u2192 4s\u00b2<\/li>\n\n\n\n
  • 3d orbital<\/strong>: 2 electrons \u2192 3d\u00b2<\/li>\n<\/ul>\n\n\n\n

    So, the full configuration for Titanium is:<\/p>\n\n\n\n

    1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u00b2 3d\u00b2<\/strong>, or using noble gas shorthand:<\/p>\n\n\n\n

    Ar\\text{Ar}Ar 4s\u00b2 3d\u00b2<\/strong><\/p>\n\n\n\n

    This is the ground-state configuration, where electrons occupy the lowest energy orbitals available. The 4s orbital is filled before 3d because it is lower in energy when empty or half-filled. Later in chemical bonding, this order can sometimes shift, but for the isolated atom in its ground state, this is the correct arrangement.<\/p>\n\n\n\n

    Let\u2019s now eliminate the incorrect choices:<\/p>\n\n\n\n

      \n
    • ArArAr 3d\u2074<\/strong>: Incorrect, only 2 electrons are in the 3d orbital.<\/li>\n\n\n\n
    • ArArAr 4s\u00b2 3d\u00b2<\/strong>: \u2714\ufe0f Correct.<\/li>\n\n\n\n
    • ArArAr 4s\u00b2 4p\u00b2<\/strong>: Incorrect, 4p comes after 3d and would not be occupied at this stage.<\/li>\n\n\n\n
    • ArArAr 4s\u00b2 4d\u00b2<\/strong>: Incorrect, 4d orbitals are much higher in energy and are not filled for Ti.<\/li>\n<\/ul>\n\n\n\n

      \u2705 Correct answer: ArArAr 4s\u00b2 3d\u00b2<\/strong><\/p>\n\n\n\n
