Question

The electronic configuration of elements A= 2,8,6 B= 2,8,8 C= 2,8,8,1 D= 2,7 . Answer the following questions: (a) What type of bond is formed when element C combines with element D? (b) Which element is an inert gas? (c) What will be the formula of the compound between A and C? ​

Answer 1

Answer:

(a) When element C combines with element D, an ionic bond is formed between them by transfer of one electron from element C atom to element D atom.

(b) Element B is an inert gas because it has 8 electrons in its valence shell; i.e, it contains completely filled valence shell.

(c) Formula of the compound will be AC2. Because element A needs two electrons to complete its octet, two atoms of element C donate two electrons to element A and get stabilised.
