By observing the Bohr Models for the elements Potassium and Nitrogen below, Potassium has  valence electron(s) and Nitrogen has  valence electron(s). If these two substances were form an ionic bond in a chemical reaction, the resulting chemical formula for the substance produced (Potassium Nitride) would have  Potassium atom(s) and  Nitrogen atom(s).

For a Bohr atom, find the variation of – (mathematical as well as nature of graph)a. Rn vs Vn b. Ln vs Vn c. Ln Vs. Rn d. C.F. Vs Vn

Two elements A and B have similar chemical properties. They don't form solid hydrogencarbonates, but react with nitrogen to form nitrides. A and B, respectively, are :Na and RbNa and CaCs and BaLi and Mg
