The maximum covalency and highest oxidation state possible for an element with $Z=13$ are respectively.
The maximum covalency and highest oxidation state possible for an element with $Z=13$ are respectively.
$3,+6$
$4,+3$
$6,+3$
$4,+2$
Solution
Electronic configuration of
$Z=13 \text { is } 1 s^2 2 s^2 2 p^6 3 s^2 3 p^1$
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 .
