One oxygen atom is unstable
since it has only 6 electrons in the outermost shell. For an atom to be stable it needs 8 electrons. So, for the oxygen atom to be stable it requires two more electrons in the valence shell.
Why a molecule of oxygen is stable but an atom of oxygen is unstable?
It
is very reactive and unstable due to its electronegativity
. It shares ist electrons with other elements and forms oxides. It is said to be monoatomic. It has a high tendency to react with other nascent oxygen to form an oxygen molecule (O
2
), which is quite stable.
Why is an oxygen molecule more stable?
In simple terms, by sharing tow pairs of bonding electrons,
the two oxygens in the molecule achieve full orbitals
, which makes them more stable i.e. the molecule is at a lower energy level than the individual atoms.
Is O more stable than O2?
Thus
O2
is thermodynamically more stable than O22+ and two free electrons because the decrease in energy caused by the electrons occupying the highest unoccupied molecular orbitals is (much) greater than any possible decrease in the bond energy.
Is an oxygen molecule stable?
Usually any atom needs 8 electrons in its outer orbit in order to stay stable. But, the Oxygen atom has 6 electrons in its outer orbit. … So, it makes
a bond with another oxygen atom and shares 2 electrons each and becomes stable
.
Why does oxygen have two atoms?
Two covalent bonds form between the two oxygen atoms because
oxygen requires two shared electrons to fill its outermost shell
. … It gets these four from four hydrogen atoms, each atom providing one. These elements all share the electrons equally, creating four nonpolar covalent bonds.
Is 02 an atom or molecule?
Molecule
: more than one atom, e.g., O2, H2, CO, H2O. Compound: more than one kind of atom in a fixed ratio, e.g., H2O, CO, etc. Not all molecules are compounds, e.g., O2.
What is the most stable oxidation state of the oxygen atom?
The oxidation state for a pure ion is equivalent to its ionic charge. In general, hydrogen has an oxidation state of +1, while oxygen has an oxidation state of
-2
. The sum of the oxidation states for all atoms of a neutral molecule must add up to zero.
Why oxygen is usually found as a molecule?
Oxygen is found naturally as a molecule.
Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O
2
. Oxygen is normally found as a molecule. It is called dioxygen.
Can an oxygen atom exist on its own?
Oxygen is an element. All its atoms are oxygen atoms. However,
they do not exist separately
. Instead, they pair up to form oxygen molecules (O
2
).
Is C2 stable or unstable?
Is C2 stable or unstable? c2 molecule exist in space as gas, but under normal environment it cannot exist as 4 electron bonding with another 4 electron (quadruple bond) is not stable due to large repulsion between electron (same charge repel) and
is very unstable
.
Is b2 or O2 2 more stable?
O
2
+
is more stable
than O
2
–
. Because According to molecular orbital theory O
2
+
has 15 electrons &it has one electron in antibonding orbital. … If number of electrons more in antibonding orbital the molecule become unstable.
Why is O2 more stable than N2?
As
bond order of nitrogen is more than
that of oxygen, nitrogen is more stable than oxygen.
Is F2 or F2+ more stable?
Between F2, F2+, and F2_ which do you think would have the highest bond order, strongest bond, longest bond length. … Therefore
F2+ will have the
highest bond order and strongest bond F2- will have the weakest bond and therefore the longest bond.
How many oxygen atoms do we breathe in?
One out of every 21 quadrillion hydrogen atoms (2.1 × 10
16
atoms) come from your body. One out of
every 26 quadrillion oxygen atoms
(2.6 × 10
16
atoms) come from your body.
