Determine the name and symbol of the element with atomic number $103$.

The outermost shell electronic configuration of a transition element is:

Consider $n$ as the number of lone pairs of electrons present in the equatorial position of the most stable structure of $ClF_3$. The ions from the following with $n$ number of unpaired electrons are :
$A. V^{3+}$
$B. Ti^{3+}$
$C. Cu^{2+}$
$D. Ni^{2+}$
$E. Ti^{2+}$
Choose the correct answer from the options given below :

In the ground state of cobalt atom $(Z = 27)$ there are $.......$ unpaired electrons and thus the atom is $.......$
