What is an octet Class 10?
i) Octet rule : “The atoms of element tend to undergo chemical changes that help to leave their atoms with eight outer shell electrons”.
What do you mean by Duplet and octet?
The key difference between octet and duplet is that octet is an atom or an ion having a maximum of eight electrons in the outermost shell while duplet is an atom having the maximum of two electrons in the outermost shell. CONTENTS.
What is octet Class 8?
The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons.
What is octet rule PDF?
• Octet rule: Atoms in a compound will. lose, gain or share electrons in order to. achieve a stable noble gas configuration.
Why is it called an octet?
An octet is unit of digital information equal to exactly eight bits. The number of bits in a byte varies according to the computer architecture, and may range from four to ten. So, the term octet was created clear up any confusion, specifying a byte of exactly eight bits.
What is an octet Class 9 Ncert?
OCTET: The possessing of 8 electrons in the outermost shell of an atom to make the shell fully filled is called as octet.
What is Duplet Class 9?
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 Duplet rule Class 9?
Duplet rule states that an element is stable if its atom has 2 electrons in its valence shell and to attain this state, elements lose, gain or share electrons and form chemical bonds. This rule is also called the duet rule. The only elements known to follow the this rule are Hydrogen, Helium and Lithium.
What is octet theory class 11?
The Octet rule states that main group elements try to bond with other atoms or species in such a way that all of them will possess stable electronic configuration. In other words we can also say that eight electrons in the outermost shell or valence shell of each atom.
What is Lewis octet rule Class 9?
Explanation of the Octet Rule The octet rule states that the atoms like to have eight electrons only in their full outer shells. For achieving eight electrons in their outer shells, atoms would gain or lose the valence electrons.
