प्रश्न
Element X has electronic configurations 2, 8, 18, 8, 1. Without identifying X,
- Predict the sign and charge on a simple ion of X.
- Write if X will be an oxidizing agent or a reducing agent. Why?

उत्तर
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 1 proton.
b. X will be a strong reducing agent as it has the tendency to donate its valence electron.
