The maximum covalency and highest oxidation state possible for an element with Z=13 are respectively.

Options

  1. A3,+6
  2. B4,+3
  3. C6,+3
  4. D4,+2

Correct answer

C. 6,+3

Step-by-step solution

Electronic configuration of Z=13 is 1 s^2 2 s^2 2 p^6 3 s^2 3 p^1 The maximum covalency of any element is found by counting the number of covalent and coordinate bonds that it can form. So, the maximum covalency of element having Z=13 is 6 . Since, it has 3 electrons in the valence shell, its highest oxidation state is +3 .
