The electronic configuration of two elements A and B are 2,8,3 and 2,8

1.	The electronic configuration of two elements A and B are 2,8,3 and 2,8,7 respectively. Find the atomic number of these elements. State the nature and formula of the compound formed by the union of these two elements.
Answer» The electronic configuration of ELEMENTS A IS 2,8,3 means ATOMIC no is = 13 which is AL (Aluminium ) element B has electronic configuration 2,8,7 means atomic no is = 17 , which is of chlorine . The COMPOUND formed is Al Cl₃ nature of the compound will be covalent .

Answer»

The electronic configuration of ELEMENTS A IS 2,8,3

means ATOMIC no is = 13 which is AL (Aluminium )

element B has electronic configuration 2,8,7

means atomic no is = 17 , which is of chlorine .

The COMPOUND formed is Al Cl₃

nature of the compound will be covalent .
