HELP Whats the diff. between O and O2?

Question

What is the difference between O and O2? They are both forms of oxygen I know. But what are all of their differences?

Forms, formulas, properties, atomic masses, names?

ANy Would be helpful and,
Whoever gives me the most differences gets best answer

Answer 1

oxygen is an element, O would be one atom of this element

O does not really exist for very long in nature, because it has only 6 electrons. it reacts with almost anything that it comes in contact with.

O2 is simply two oxygen atoms double bonded together to complete their outer shells. the atmosphere we breath is 20% O2. there is no O in the atmosphere, or anywhere else for that matter.

you can find out all about it and see pictures here

Answer 2

O is an Ion and is very unstable and O2 is the molecule

The 0 Ion has an attomic mass of 15.999 Atomic untis whereas O2 has Twice that. The O2 forms when O forms co-valent bonds with itself. These are generally strong and usually require an external input such as heat, spark, or electrochemical reaction in order to break. The properties are quite similar, the defining difference is the ease with which they react. This is due to differing electronegativites of the two substances. Both are flammable and soluble in water to a small degree. Also in liquid form oxygen becomes magnetic.

O also has a much smaller Atomic radius than the molecule and is thus easier to combine in alloys with other materials.

Answer 3

O and O2 is that O2 is two oxygen atoms bonded in a covalent bond with the mass as twice as much and called dioxide

Answer 4

"o" is an oxygen element, "o2" is a combination of two oxygen elements, creating oxygen in the air.

I would think they have the same forms and properties, maybe not, assuming both are made up of the oxygen element

"o2" is twice the atomic mass of "o", which is ("o" is) 16.00 (i think)

Answer 5

If you can find "O" by itself, then you have what is called atomic oxygen. This happens only in high energy condition: high heat or presence of ionizing energy. That means atomic oxygen is extremely reactive.
