Why is o not stable?

Why is o not stable?

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 does O2 exist but not S2?

In O2​(O=O), due to the small size of oxygen, strong p-p bonding is possible, but in S2​, due to the larger size of sulphur, there is no strong p-p bonding. So, bond is weak and breaks down. Was this answer helpful?

Which anion is more stable towards water?

O2​2−

Is K stable in water?

Potassium is weakly hazardous in water, but it does spread pretty rapidly, because of its relatively high mobility and low transformation potential. Potassium toxicity is usually caused by other components in a compound, for example cyanide in potassium cyanide.

Which is stable in water?

The stable water isotopes deuterium and oxygen-18 are suitable tracers in the water cycle and can also be used to track climate changes. Deuterium and oxygen-18 are also being increasingly used worldwide to record climate-related changes in the water cycle. …

Which is most stable in water?

Water has two hydrogen and one oxygen which means it dissolves substance that has the ability to donate electrons but crystal field spiting concept applies in case of Cr3+ . According to the theory, it has t2g in half filled. So, it has no electrons to donate which makes it more stable in water.

Which is more stable Mn2+ or Cr3+?

ANS: (i) It is because Cr2+ loses electron to become Cr3+ which is more stable due to half filled t2g orbitals, whereas Mn3+ will gain electron to become Mn2+ which is more stable due to half filled Page 2 2 d-orbitals.

Is O 2 stable towards water?

All the three O2−,O2​2− and O2​− are unstable in presence of water and abstract proton from water.

How stable is H2O?

The tremendous energy that is released is a signal that hydrogen and oxygen are very eager to become water. Another way of saying that is that water is an extremely stable compound, compared with loose molecules of hydrogen and oxygen. It is hard to break water molecules apart into its components.

Is water part oxygen?

Although water molecules contain an oxygen atom, this oxygen is not what is needed by aquatic organisms living in natural waters. A small amount of oxygen, up to about ten molecules of oxygen per million of water, is actually dissolved in water.

Which is more stable H2S or H2O?

the Water H2O molecules strongly attract each other through intermolecular H bonding which is not present in H2S molecule. water molecule is more stabilized due to strong hydrogen bonding. So the thermal stability of H2O molecule is more.
