Why do oxygen atoms exist for longer periods of time in the upper atmosphere than in the stratosphere?
Oxygen atoms in the upper atmosphere (thermosphere/exosphere) have lower collision rates with other atoms or molecules due to the low density of particles, allowing them to exist longer. In the stratosphere, oxygen atoms react quickly with other molecules, such as ozone, which stabilizes the oxygen atoms into ozone molecules, so their lifespan is shorter.
Molecules is created by atoms or molecules?
Atoms. Some atoms can not exist without another atom/s to stabilise it and form a molecule For example, the O2 (oxygen) molecule consists of two O (oxygen) atoms. The H2O (water) molecule consists of two H (hydrogen) atoms and one O (oxygen) atom.
Are molecules only found in compounds?
No, molecules can exist both in compounds and as individual elements. In compounds, molecules are formed when atoms chemically bond together. In the case of elements, some exist as diatomic molecules (like oxygen, O2), while others exist as single atoms (like helium, He).
What are the total number of atoms in two oxygen molecules?
There are 4 oxygen atoms in two oxygen molecules.
How many oxygen atoms are there in dioxide molecules?
There are 2 oxygen atoms in dioxide
Do all element exist as atom?
If you mean do the exist as single atoms, no. Some can exist as molecules. Hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine usually exist as the diatomic molecules H2, N2, O2, F2, Cl2, Br2, and I2 respectively. Oxygen can also exist as O3. Phosphorus can exist as P4 and arsenic as As4. Sulfur is usually found as S8. Carbon can exist as C60 and a variety of similar molecules.
Why oxygen nitrogen exist in molecular state?
Oxygen and nitrogen are diatomic molecules, meaning they exist as molecules consisting of two atoms of the same element bonded together. Oxygen forms O2 molecules while nitrogen forms N2 molecules due to the stability achieved through electron sharing in the covalent bonds between the atoms. This molecular form allows them to exist in a gaseous state at room temperature and pressure.
Why atoms and molecules are invented?
The were not invented, they exist. Atoms and molecules were discovered.
How many carbon atoms are in a molecule of maltose if the molecules has 12 oxygen atoms?
There are 12 carbon atoms in a molecule of maltose. Each carbon atom forms a total of four bonds, which include bonds with other carbon atoms, hydrogen atoms, or oxygen atoms. With 12 oxygen atoms present, these atoms would be accounted for in the molecular structure of maltose as well.
Is rust made of separate atoms or molecules?
Rust is primarily composed of iron oxide, which consists of iron and oxygen atoms bonded together in a specific arrangement. While iron and oxygen exist as individual atoms, in rust, they combine to form molecules. Therefore, rust is made up of these molecules rather than separate atoms.
Are hydroxide atoms positive or negative?
Negative. Hydroxide atoms also don't exist, they're molecules. They consist of two atoms, one hydrogen atom and one oxygen atom. The charge is -1 on the oxygen.
How many atoms are in an oxygen molecule O2?
Molecules of oxygen exist in two relatively stable allotropes: breathable oxygen with the formula O2, and ozone with the formula O3. The little number indicates that these molecules are composed of (respectively) two or three oxygen atoms.
