Answer
(a) X+ Reason — Since the element X has 1 electron in its valence shell. So, it will lose an electron and gain noble gas configuration. Therefore it forms a cation (X+). The sign is positive and the charge is of 1 proton.
(b) X will be a strong reducing agent as it has the tendency to donate its valence electron.
