Elements in the third period or beyond (Si and beyond) in the periodic table can form compounds with expanded octets. This includes elements such as sulfur, phosphorus, chlorine, and xenon. These elements can often exceed the octet rule by forming more than 8 electrons in their valence shell in some compounds.
To complete their octet
1. the incomplete octet of a central atom 2. odd electron molecule 3. compound with expanded octet 4. acc. to rule atoms complete their octet to complete their octet to become stable like inert gas, but it is seen that inert gases like xenon are not stabkle they combine with fluorine and oxygen to form no. of compounds. 5. shape of molecule cant be explained 6. stability of molecule cant be explained
compound
No, xenon does not always follow the octet rule. It is a noble gas and can form stable compounds that have more than eight electrons around the xenon atom, known as expanded octet.

Elements which have d-orbitals (i. e. n=3 or higher) can form compounds with an expanded octet. Some examples are;Phosphorous Pentachloride PCl5Sulfur Hexafluoride SF6Dichloro Heptoxide Cl2O7
Phosphorus can have an expanded octet because it has empty d orbitals in its valence shell, allowing it to accommodate more than eight electrons and form more than four bonds.

the properties of a compound are not the same as the elements that form them.
No, xenon does not always follow the octet rule. It is a noble gas and can form stable compounds that have more than eight electrons around the xenon atom, known as expanded octet.
a compound
A compound forms when two or more different elements chemically bond together. Therefore, at least two elements must be present for a compound to form.
After a chemical reaction two elements form a chemical compound.
Xenon can achieve a stable octet by forming compounds with elements that can share their electrons with xenon. For example, xenon can form compounds with fluorine, chlorine, or oxygen where xenon acts as the central atom and bonds with these more electronegative elements to complete its octet.
