What is the Lewis structure for SO3 2?
What is the Lewis structure for SO3 2?
so32- ion. Central atom of SO32- ion is sulfur. Around sulfur atom, there are four bonds and a single lone pair in the lewis structure of SO32- ion. Therefore, five electron groups are around the central atom of SO32- ion.
Is sulfur trioxide ionic or covalent?

| CH4 | Covalent |
What is Duplet configuration?
There is another rule, called the duplet rule, that states that some elements can be stable with two electrons in their shell. Hydrogen and helium are special cases that do not follow the octet rule but the duplet rule. They contain an s s s orbital but no p p p orbitals.
What is difference between Duplet and octet?
Octet means presence of a total of 8 electrons in its valence shell while in case of duplet only 2 electrons are present in valence shell.
Why Duplet is applied in K shell?
the tendency for atoms to have 2 electrons in their outermost shell by interacting with other atoms through electron sharing or transfer is known as duplet rule. IF AN ATOM HAS 2 ELECTRONS IN ITS OUTERMOST SHELL THEN IT IS CALLED DUPLET RULE AND IF 8 ELECTRONS IN ITS OUTERMOST SHELL THEN IT IS CALLED OCTET RULE.
Why Duplets are called so?
Filling the outer k-shell (the first shell/energy level/orbit which can have 2 electrons at most) with a total of 2 electrons is called “duplet rule” or “duet rule”. Hydrogen atoms have 1 electron in their K-shell naturally, if they gain one more electron, they will have 2 electrons.
Why does lithium follow octet rule?
The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas. Lithium tends to lose one electron to take on the electron configuration of the nearest noble gas, helium, leaving it with two valence electrons.
What is meant by Duplet?
Definition of ‘duplet’ 1. a pair of electrons shared between two atoms in a covalent bond. 2. music. a group of two notes played in the time of three.
What is a Duplet in chemistry?
Duplet state is when an element has two electrons in its outermost shell. Example: Helium (2): Electronic configuration is 2. So, helium has 2 electrons in the outermost shell. That is helium is in its duplet state.
What is meant by octet?
Octet, in chemistry, the eight-electron arrangement in the outer electron shell of the noble-gas atoms. This structure is held responsible for the relative inertness of the noble gases and the chemical behaviour of certain other elements.
What is Duplet state?
A duplet state is when an element has 2 electrons in it’s outer most she’ll e.g for helium. An octet state is even more stable than a duplet state due to reduced electron repulsion hence more stability.
How do elements gain stability?
The stability of atoms depends on whether or not their outer-most shell is filled with electrons. If the outer shell is filled, the atom is stable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability.
What is octet rule explain with an example?
The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons. The shared electrons fulfil the valency requirements of both the bonded atoms. Thus, it can be noted that both the oxygen atoms and the carbon atom have an octet configuration in the CO2 molecule.
What is octet Why is it inactive?
Octet is inactive because it has a filled shell of electrons or the atom doesn’t need to either gain electrons.
