Octet Rule states that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. Depending on this fact answer the following question : 
1)What is an incomplete octet?
2)What is an odd-electron molecule?
3)Why are there extra electrons in the expanded octet?
​

Respuesta :

Answer:

1. an incomplete octet is an valence shell that is not fully stable since it doesn't have 8 electrons

2.an odd electron molecule is a molecule that has an odd number of electrons but is still stable

3. there are extra electrons in an expanded octet because the molecules' central atoms make extra bonds that don't comply with the octet rule.
