…are expressed by his celebrated octet rule, which states that
electron transfer or electron sharing proceeds until an atom has acquired an octet of electrons
(i.e., the eight electrons characteristic of the valence shell of a noble gas atom). When complete transfer occurs, the bonding is ionic.
What does the octet rule state quizlet?
What does the octet rule state that explains why atoms bond?
An atom bonds to have eight valence electrons to become stable
. … The third shell would be empty so that the eight electrons in the second level would be outermost after the atom loses one electron.
What is the octet rule simple?
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. … Atoms of metals tend to lose all of their valence electrons, which leaves them with an octet from the next lowest principal energy level.
What is octet state with example?
In chemistry, the octet rule explains how atoms of different elements combine to form molecules. … In a chemical formula, the octet rule strongly governs the number of atoms for each element in a molecule; for example, calcium fluoride is
CaF2
because two fluorine atoms and one calcium satisfy the rule.
What does the octet rule state chegg?
The octet rule states that
atoms in molecules share electrons in such a way that each atom has a full valence shell
.
What is the stable 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.
How do you know if a octet is satisfied?
To satisfy the octet rule,
atoms must fill their valence shell with electrons
.
What is the octet rule flashcards?
Octet Rule. States that
atoms must attain 8 electrons in outermost energy level to become stable
.
Subatomic Particles
. Particles SMALLER than an atom.
Which element can violate the octet rule?
The two elements that most commonly fail to complete an octet are
boron and aluminum
; they both readily form compounds in which they have six valence electrons, rather than the usual eight predicted by the octet rule.
Which element is satisfying the octet rule?
Hydrogen
, the only element in the first row besides Helium, fulfills the “octet rule” by sharing two electrons only. Two hydrogen atoms form a covalent bond to make a hydrogen molecule. Each contributes one electron and forms a system that is much more stable than the isolated atoms.
What is octet rule Toppr?
The octet rule refers to an
important principle that the atoms which have bonded share eight outer electrons
. This certainly means that the atom’s valence shell has a resemblance with a noble gas. The octet rule states that the atoms like to have eight electrons only in their full outer shells.
What is octet rule for kids?
The octet rule is a general rule of thumb that applies to most atoms. It states that
every atom might want to have eight valence electrons in its outermost electron shell
.
Which follows octet rule?
Elements that obey octet rules are main group elements which are
oxygen, carbon, nitrogen
. s-block and p-block elements obey octet rule except for hydrogen, helium, and lithium.
Which atom in sodium lauryl sulfate has an expanded octet?
Question: Art Sodium lauryl sulfate is used in shampoos and cleansers. The structure of sodium lauryl sulfate is H H H H H H H H H H H 01 I LLLLLLL _o T 9 -0-0-0-0-0-0-s=8 Which atom in sodium lauryl sulfate has an expanded octet?
O carbon
.
Atoms tend to gain, lose, or share electrons until they are surrounded by
four valence electrons
. Atoms tend to share electrons until they are surrounded by ten valence electrons.
Octet rule: A rule stating that atoms lose, gain, or share electrons in order to
have a full valence shell of 8 electrons
. (Hydrogen is excluded because it can hold a maximum of 2 electrons in its valence shell. )
