Question

What is meant by the Octet Rule and Expanded Rule in Chemistry?? and the chapter is Chemical Bonding​

Answer 1

Answer:

Main group elements that form more bonds than would be predicted by the octet rule are called hypervalent compounds, and have what is known as an 'expanded octet,' meaning that there are more than eight electrons around one atom.

Answer 2

Answer:

The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
