Write the electronic configuration two elements X and Y whose atomic numbers are 20 and 17 respectively. Write the Molecular formula of the compound formed when element. X reacts with element Y. Draw electron-dot structure of the product and also state the nature of the bond formed between both the elements.


Atomic number of X = 20, electronic configuration = 2, 8, 8, 2
Atomic number of Y = 17, electronic configuration = 2, 8, 7
Molecular formula of the compound = XY2
Electron-dot structure of the compound:

An ionic bond is formed between the two elements.
