How many moles of krypton do you have if you have 9.15 x 1024 atoms of krypton?
The answer is 15,2 moles.
Are neutrons found only in atoms?
No, neutrons are not only found in atoms. Neutrons are subatomic particles and can also exist independently in environments such as nuclear reactors or certain types of particle accelerators.
What do atoms form when they stick together?
Atoms form molecules when they stick together through chemical bonds. Molecules are the smallest units of a compound that can exist independently and possess unique chemical properties based on the atoms they are composed of.
Why do noble gases exist independently in nature?
Noble gases have completely filled orbitals. They are stable, chemically inert, do not generally form compounds and hence exist as isolated atoms.
Why molecules are independently exist but why not atom?
Molecules are formed when two or more atoms chemically bond together. Atoms are not typically found in isolation because they tend to interact with other atoms to form stable structures such as molecules. This is due to the tendency of atoms to fill their outer electron shells by forming bonds with other atoms.
Why can some atoms exist independently?
bcz their energy is low thats why they can exist independently while the energy of some atoms is so high that they can only exist as ions or molecuoles not as free atoms
Why can't all atoms exist independently while all molecules exist independently?
Atoms cannot exist independently because all atoms strive for a full outer shell of electrons through bonding with other atoms. Molecules can exist independently because they are stable structures formed from atoms through covalent or other types of bonding. This bonding enables molecules to have a stable arrangement of atoms.
How many atoms are in a krypton molecule?
Krypton is in Group 8 of the Periodic table, along with other Noble Gases such as Helium and Neon. Group 8 are known as the Noble Gases as they have a full outer shell of electrons, and don't need to bond to other atoms to full up their electrons, so they exist as single gaseous atoms. So, how many atoms are there in a Krypton molecule? One (it's technically not a molecule, but an atom, you don't get Krypton molecules!)
What molecule exist independently?
Noble gases, such as helium and neon, exist as single atoms due to their stable electron configurations. Oxygen and nitrogen also exist independently as diatomic molecules (O2 and N2) in the Earth's atmosphere.
Why these gases argon krypton exist as monoatomic molecules?
Argon and krypton are noble gases, which have full outer electron shells and exist as monoatomic molecules because they are chemically stable and do not form bonds with other atoms easily. This stability is due to their electron configuration, which makes them content with existing as individual atoms rather than forming bonds with other atoms to complete their electron shells.
What elements exist as single atoms not bonded to other atoms?
Noble gases such as helium, neon, argon, krypton, and xenon exist as single atoms not bonded to other atoms. They are stable with a full outer electron shell, making them unreactive and existing as individual atoms in their natural state.
Can unicellular organisms exist independently?
Yes, single-celled organisms can exist independently.
Why atoms of most of the elements do not exist independently?
Atoms of most elements do not exist independently because they are more stable and energetically favorable when they form chemical bonds with other atoms. These bonds allow atoms to achieve a full outer electron shell and attain a lower energy state. This results in the formation of molecules or compounds rather than isolated atoms.
How many moles of krypton do you have if you have 9.15 x 1024 atoms of krypton?
The answer is 15,2 moles.
Which molecules contain the fewest covalent bonds?
Noble gases such as helium, neon, argon, krypton, xenon, and radon contain the fewest covalent bonds because they exist as monatomic molecules, meaning they exist as single atoms rather than bonded pairs of atoms.
Why does hydrogen molecule does not exist?
Hydrogen molecules do exist but they are less stable than hydrogen atoms. This is because hydrogen molecules require a large amount of energy to form since hydrogen atoms are highly reactive and tend to exist independently. Additionally, hydrogen molecules can easily dissociate into individual atoms at lower temperatures.
Does one mole of krypton atoms has a mass of 41.90g?
No, the molar mass of krypton (Kr) is approximately 83.80 g/mol, so one mole of krypton atoms would have a mass of 83.80 grams.
