Which is more stable o2 or o2+?
O2+ is more stable than O2-.
Reason: According to molecular orbital theory O2+ has 15 electrons &it has one electron in antibonding orbital.
In the case of O2- 17 electrons are present &3 electrons are present in antibonding orbitals.
If number of electrons more in antibonding orbital the molecule become unstable..
Can atomic oxygen breathe?
The oxygen that we breathe is called O2—that is, it is comprised of two atoms of oxygen. O3 is ozone, such as occurs in Earth’s upper atmosphere, and O (one atom), is atomic oxygen. Atomic oxygen doesn’t exist naturally for very long on the surface of Earth, as it is very reactive.
Can we see oxygen?
Since no light of that wavelength gets to us, there is no reason for us to evolve eyes that respond to that kind of light. And even if our eyes could see that kind of light, there wouldn’t be any for use to see oxygen with. Therefore, we cannot see oxygen.
Is beryllium stable or unstable?
Beryllium is the only stable light metal with a relatively high melting point. Although it is readily attacked by alkalies and nonoxidizing acids, beryllium rapidly forms an adherent oxide surface film that protects the metal from further air oxidation under normal conditions.
In which form oxygen is stable?
Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natural abundance).
What is the same about oxygen 16 17 and 18?
Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. … Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
Why is oxygen 15 unstable?
Oxygen-15 undergoes positron decay because it has too few neutrons for the number of protons. … Oxygen-15 has 7 neutrons and 8 protons. It is unstable because it is below the band of stability.
Is oxygen stable or reactive?
Chemical Properties of Oxygen Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. As such, it readily forms compounds (notably, oxides) with almost all other elements.
Is oxygen 16 stable or unstable?
Oxygen-16 (16O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus. It has a mass of 15.99491461956 u. Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance.
Is hydrogen stable or unstable?
Hydrogen only has one electron in its lowest energy level. This is a very unstable arrangement, and hydrogen gas undergoes a variety of reactions so as to reach a stable electron configuration where its energy level is either empty of electrons, or filled with electrons.
Who named Oxygen?
Antoine-Laurent LavoisierIn 1775–80, French chemist Antoine-Laurent Lavoisier, with remarkable insight, interpreted the role of oxygen in respiration as well as combustion, discarding the phlogiston theory, which had been accepted up to that time; he noted its tendency to form acids by combining with many different substances and accordingly …
Who invented oxygen?

Does Mars have oxygen?
The atmosphere of Mars is the layer of gases surrounding Mars. It is primarily composed of carbon dioxide (95.32%), molecular nitrogen (2.6%) and argon (1.9%). It also contains trace levels of water vapor, oxygen, carbon monoxide, hydrogen and other noble gases.
Why is o2 unstable?
O is unstable bcz of its incomplete filling of electrons soo it wil definitely react wit any of d element to attain stable configuration.. therefore.. its nt available freely in d atmosphere.. whereas O2 is stable..
Is oxygen unstable?
A single atom of oxygen is unstable – it wants to combine with something else. That is why oxygen is almost always found in pairs as O2. Ozone is made of three oxygen atoms and indicated with the symbol O3. It is not stable and is prone to losing an oxygen atom, becoming an oxygen molecule (O2).
Do we breathe the same air?
According to theoretical physicist Lawrence Krauss, the answer is almost 100% yes! His research supports the theory that the molecules we breathe are redistributed evenly in our atmosphere within a number of centuries.
Can you breathe in space?
Whatever you do, don’t hold your breath! The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. … Without air in your lungs, blood will stop sending oxygen to your brain.
Is MG 2 more stable than MG?
Mg is more stable because it is neutral atom while Mg^+2 to be stable will loses two electrons readily.
Is Neon a stable element?
Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).
Why lighter nuclei are unstable?
In summary it is the balance of protons and neutrons in a nucleus which determines whether a nucleus will be stable or unstable. … Too many neutrons or protons upset this balance disrupting the binding energy from the strong nuclear forces making the nucleus unstable.
How do you know if an atom is stable or unstable?
An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.
