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

Correct Answer:<\/h3>\n\n\n\n

Titanium (Ti), Atomic Number 22:<\/strong>
Electron configuration:
1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 3d\u00b2 4s\u00b2<\/strong><\/p>\n\n\n\n

Vanadium (V), Atomic Number 23:<\/strong>
Electron configuration:
1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 3d\u00b3 4s\u00b2<\/strong><\/p>\n\n\n\n

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

The electron configuration of an atom shows how its electrons are distributed among different atomic orbitals. These configurations follow three essential rules: the Aufbau principle, Pauli exclusion principle, and Hund’s rule.<\/p>\n\n\n\n

The Aufbau principle<\/strong> states that electrons fill orbitals starting from the lowest energy level to higher ones. For most elements, the filling order is:<\/p>\n\n\n\n

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

Now, let\u2019s apply this to Titanium (Ti)<\/strong>. Titanium has an atomic number of 22, meaning it has 22 electrons in its neutral form. Filling the orbitals in order of increasing energy:<\/p>\n\n\n\n

    \n
  • 1s\u00b2 (2 electrons)<\/li>\n\n\n\n
  • 2s\u00b2 (2 electrons)<\/li>\n\n\n\n
  • 2p\u2076 (6 electrons)<\/li>\n\n\n\n
  • 3s\u00b2 (2 electrons)<\/li>\n\n\n\n
  • 3p\u2076 (6 electrons)<\/li>\n\n\n\n
  • 4s\u00b2 (2 electrons)<\/li>\n\n\n\n
  • 3d\u00b2 (2 electrons)<\/li>\n<\/ul>\n\n\n\n

    This gives the configuration: 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u00b2 3d\u00b2<\/strong>
    Or rearranged as: 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 3d\u00b2 4s\u00b2<\/strong><\/p>\n\n\n\n

    Next is Vanadium (V)<\/strong> with atomic number 23. This means 23 electrons in the neutral atom. Starting with the same sequence as above, we continue:<\/p>\n\n\n\n

      \n
    • 1s\u00b2 through 3p\u2076 (already 18 electrons)<\/li>\n\n\n\n
    • 4s\u00b2 (2 electrons) \u2192 total now 20<\/li>\n\n\n\n
    • 3d\u00b3 (3 electrons) \u2192 total becomes 23<\/li>\n<\/ul>\n\n\n\n

      So the configuration is: 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 3d\u00b3 4s\u00b2<\/strong><\/p>\n\n\n\n

      Both elements are transition metals, and their electron configurations reflect partial filling of the 3d subshell, a key feature of these elements.<\/p>\n\n\n\n
