The configuration of an element is given here. 

(a) What is the identity of the element? 

(b) In what group and period is the element found? 

(c) Is the element a nonmetal, a main group element, a transition metal, a lanthanide, or an actinide?

(d) Is the element diamagnetic or paramagnetic? If paramagnetic, how many unpaired electrons are there? 

(e) Write a complete set of quantum numbers (n, ℓ, m_ℓ, ms) for each of the valence electrons. 

(f) What is the configuration of the 2+ ion formed from this element? Is the ion diamagnetic or paramagnetic?
