Question
An element A has the configuration 1s22s22p63s1 while the configuration of B is 1s22s22p5. What type of bond is likely to be formed between them?
Solution
On the basis of electronic configuration, the atom A has only one electron in its valence shall and atom B has seven electrons in its valence shell. Thus, one electron from A gets transferred to atom B. Thus A+ and B– ions are formed. These ions are held together by electrostatic force of attraction known as ionic bond. Hence bond between A and B is ionic bond.
