Each element can form stable, less stable or unstable compounds.
Atoms
Many of the elements with higher atomic numbers have no stable form yet discovered, ex: ununoctium.
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
Polymers are formed from monomers.
Most of the metals can occur in the native and combined forms.
It forms an octet / stable electronic configuration
Many of the elements with higher atomic numbers have no stable form yet discovered, ex: ununoctium.
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
A compound forms whenever 2 or more different elements are chemically bonded.
They create molecules. If the atoms joined together are from different elements they create polar molecules.
Most often, at least one chemical compound.
Group 17 (7A), the halogens.
Yes. Cobalt forms many salts and some other compounds as well.
Compound change is 2 or more elements are chemically combined together and forms different properties(or not).
Elements are the most simple form of a substance. Due to nitrogen being an element only nitrogen forms nitrogen
Its a compound because it consist of two elements hydrogen and oxygen, when combined it forms water.
Sodium and iodine combined together would have the name "sodium iodide". The chemical formula would be NaI.
Oxygen becomes more stable when it forms compounds.
