question_answer 61)

    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?

Answer:

                  Atomic number of A = 19 Electronic configuration is 2, 8, 8,1 Hence, element A is metal potassium (K) and, Atomic number of B = 17 Electronic configuration is 2, 8,7 It is a non-metal, chlorine (Cl). So, the electron dot structure of KCI is The bond formed between K+ and Cl- is ionic bond and formula of the product formed K+ Cl?or KCI.
