What do you mean when you say an atom is electron deficient?
It has incomplete octet (incomplete valence shell) after bond formation.
What is electrophilic center?
It's an area of low electron density, and can be caused, for example, by an incomplete octet. Areas of high electron density are called nucleophilic centres.
Is AlCl3 hypervalent?
No, Al is a trivalent atom having three unpaired electrons in its outermost shell and forms three covalent bonds with chlorine atoms but due to incomplete octet it is unstable compound. For the completion of its octet Al atom may form a coordinate covalent bond with chloride ion (AlCl4)1- , now you can say that AlCl41- is hypervalent.
How does oxygen not follow the octet rule?
It does follow the octet rule!
How can xenon achieve stable octet?
In its ground state it does have a stable octet.
What do you mean when you say an atom is electron deficient?

What are the limitations of octet rule?
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
Which families contains a full octet of valence electrons?
These are the noble gases.
Another word for an 8 piece band?
its called an octet
What is electrophilic center?

Is nitrous oxide a single bond?
in NO molecule there is a double bond N=O but nitrogen has an unpaired electron and its octet is incomplete so it is unstable and forms N2O4 a dimer O=N-N=O
What are eight voices called?
An octet.
What are 8 singers called?
A group of eight anything is called an "octet".
Is AlCl3 hypervalent?
No, Al is a trivalent atom having three unpaired electrons in its outermost shell and forms three covalent bonds with chlorine atoms but due to incomplete octet it is unstable compound. For the completion of its octet Al atom may form a coordinate covalent bond with chloride ion (AlCl4)1- , now you can say that AlCl41- is hypervalent.
Give example of octet rule?
Az important rule: any octet has to have eight parts, otherwise it is not an octet.
Is octet a collective noun?
The noun 'octet' is a word for a group of eight. The noun 'octet' is not a standard collective noun for a specific group, but can be used as a collective noun for any group of eight; for example, an octet of singers, an octet of swans, etc.
What is a octet in poetry?
An octet is a stanza of poetry that has eight lines.
