Can CL have an expanded octet?

Can CL have an expanded octet?

The octet rule can be ‘expanded’ by some elements by utilizing the d-orbitals found in the third principal energy level and beyond. Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet.

Is CL an exception to the octet rule?

Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.

Does cl2 follow the octet rule?

Formation of dichlorine (Cl2) : The atomic number of chlorine is 17 and has 7 valence electrons, which means Cl needs one more electron to complete its octet. In order to complete its octet , each chlorine atom contributes one electron to the shared pair.

How do you find the expanded octet?

1) The central atom with an expanded octet MUST have an atomic number larger than 10 (beyond neon). 2) Extra electrons should be first placed on the outside atoms. After the outside atoms have fulfilled the Octet Rule, and there are still extra electrons, start with placing them as lone pairs on the central atom.

Why can cl have an expanded octet?

Re: Cl as an Expanded Octet Since Chlorine is in the n=3 shell, that means it can gain more electrons to put into a 3d shell, if necessary.

Can bromine have an expanded octet?

Note that in the Lewis structure for BrF5, Bromine (B) is in Period Four on the periodic table. This means it can hold more than eight valence electrons. This is called an expanded octet.

Can Oxygen expand its octet?

Now sulfur has 6 unpaired electrons which means it can form 6 covalent bonds to give a total of 12 electrons around its valence shell. Hence oxygen and other Period 2 elements do not use orbitals in the third principal quantum shell for bonding and cannot expand octet.

Is octet a pcl3?

In PCl3, the octet for both phosphorus and Chlorine atoms is complete. Therefore, it follows the octet rule.

What is the best description of the octet rule?

The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.

What is octet rule quizlet?

Octet Rule. States that atoms must attain 8 electrons in outermost energy level to become stable. Subatomic Particles. Particles SMALLER than an atom.
