element
Hydrogen is called elemental gas it is composed of single proton and single electron and can't exist in nature in single form. By pragya gk
Many atoms have electron configurations that are unstable. By sharing electrons with one or more other atoms, new, more stable electron configurations form.
Iodine doesn't exist in nature in elemental form.
Such compound does not exist in nature.
All alkali metals exist in nature as compounds.
All alkali metals exist in the nature only as compounds.But I suppose that you think to francium, an unstable and radioactive chemical element.
Yes, single-celled organisms can exist independently.
Proton normally exist in nucleus. Along with it are neutrons.
no exist,all bacterias can move independently
element
Noble gases have completely filled orbitals. They are stable, chemically inert, do not generally form compounds and hence exist as isolated atoms.
Yes: Atoms of krypton almost always do exist independently of chemical bonding to any other atoms.
The noble Gases, He, Ne, Ar, Kr, Xe, Rn.... filled valence electrons
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
Light energy can exist independently of matter. *Studyisland
