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 ?

Explanation

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
Electronicm configuration is 2,8,7
It is a non-metal, chlorine (Cl)
So, the electron dot structure of KCl is

The bond formed between `K^(+) and Cl_(-)` is ionic bond and formula of the product formed `K^(+)Cl^(-) or KCl`.
