Write the formula of the product formed when the element A (atomic number 19) combines with the element B (atomic number 17). Draw its electronic dot structure. What is the nature of the bond formed?

Element A has an atomic number 19, hence it is Potassium (K)
Element A has an atomic number 17, hence it is chlorine (Cl)
Hence, its formula will be KCl.

 The electron dot structure is given below:

Ionic bond will be formed between Chlorine and Potassium (Cl and K).
