Yes: Atoms of krypton almost always do exist independently of chemical bonding to any other atoms.
a molecules are made of atoms
The answer is 15,2 moles.
Noble gases have completely filled orbitals. They are stable, chemically inert, do not generally form compounds and hence exist as isolated atoms.
Atoms of most elements are not able to exist independently. Atoms form molecules or ions aggregate in large numbers to form the matter that we can see. Molecule is capable of independent existence.
Natural isotopes of krypton are: Kr-78, Kr-80, Kr-81, Kr-82, Kr-83, Kr-84, Kr-86.
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
a molecules are made of atoms
Many atoms have electron configurations that are unstable. By sharing electrons with one or more other atoms, new, more stable electron configurations form.
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!)
Yes, single-celled organisms can exist independently.
The only such elements are the Noble Gases (He, Ne, Ar, Kr, Xe, Rn) (that is helium, neon, argon, krypton, xenon and radon)
The answer is 15,2 moles.
No, krypton has the atomic mass of 83.798 amu. This means that one mole of krypton is 83.798 g.
no exist,all bacterias can move independently
There is sufficient chemical driving force to cause most elements to react with other elements into contact with which the elements come.
