Yes they do.
All alkali metals exist in nature as compounds.
Yes: Atoms of krypton almost always do exist independently of chemical bonding to any other atoms.
Yes, single-celled organisms can exist independently.
Yes, chemical bonds between atoms are essential for forming the variety of matter in the world. These bonds, such as ionic, covalent, and metallic bonds, determine the structure and properties of substances, leading to the vast array of compounds and materials we encounter. Without these interactions, atoms would exist independently, and the complex molecules and structures necessary for life and diverse materials would not exist.
Yes, all salts are ions because they are composed of positively and negatively charged ions. However, not all ions are salts because ions can exist independently without forming a salt compound.
Noble gases have completely filled orbitals. They are stable, chemically inert, do not generally form compounds and hence exist as isolated atoms.
No because they are elements an we need elements to live. Your welcome for your answer right? :) P.S if your looking for any more elements go chemicool.com put the name of your element and it would give you all of the answers. ;P <3
No, ionic compounds exist as a crystal lattice structure in which positively charged ions are surrounded by negatively charged ions in a repeating pattern. This structure extends in three dimensions, rather than forming discrete molecules.
no exist,all bacterias can move independently
No, for all elements the smallest particle that can exist independently is an atom.
Of course, fatty acids are organic compounds and they can not exist without carbon.
everything that exist without carbon (rocks, sand, water, etc)
