Air, water, plants, and animals are not made of rocks.
Atoms and molecules are not made of rocks, although rocks are made of them.
Sulfur is an active natural life giving element.
Naturally. Cobalt is a natural element, not man-made.It is naturally occuring.
Elements can occur in nature as pure substances, such as oxygen or gold, or as compounds when they combine with other elements to form molecules like water or carbon dioxide. Elements can be found in various forms, including solids, liquids, and gases, depending on their properties and conditions in the environment.
Yes, bromine is naturally occurring element. It is possible with technological advancement in the field of chemistry that scientists are now able to synthesize bromine in laboratory. Bromine gives M+2 peak in FT-IR.
Chlorine is a chemical element that is found in the periodic table with the symbol Cl and atomic number 17. It is a highly reactive gas that is commonly found naturally in salt compounds like sodium chloride.
helium
Nobelium is a man made chemical element.
Sulfur is an active natural life giving element.
Every element found on the Periodic Table can be found in a natural environment. None are man-made. Only compounds can be man-made.
It is synthetic; also known as "man-made".
I believe it is Uranium. All elements heavier than uranium are man-made. Here's an interesting article... http://space.newscientist.com/article/dn13828-has-the-heaviest-element-been-found.html
its an element, so yes, any thing that's not manufactured by man is natural, therefore found in nature. It is not, however, found unless forced by man; so for most practical purposes it is not found in nature.
Neodymium is a natural element and a rare-earth metal that can be found in the Earth's crust. It is not man-made.
Naturally. Cobalt is a natural element, not man-made.It is naturally occuring.
Monatomic molecules
No, Uranium is naturally occurring. But all elements beyond uranium are man-made.
The element is determined by the number of protons in its nucleus. Since molecules are made up of elements, the number of molecules has nothing to do with determining the element.
