Molecules are two or more atoms electronically combined.
Oxygen atom is just 'O'
However, oxygen does not exist as a single atom in the air, but as the molecule 'O2'. ( O=O), and in the high/upper atmosphere as ozone ( O3 ), where the three atoms are combined in a triangular formation.
NB THe Noble(Inert) gases DO Exist as single atoms (Monatomic), and NOT as molecules. e.g. Helium(He) , Neon (Ne) etc.,
weak bonding among the atoms or moecules as compare to solids make the liquids as fluids...
Water=H20 Ozone=O3 Caffeine=C8H12N403
the two atoms belong to two different elements
The atoms in a liquid are the same as the atoms in a solid. They are simply arranged in a different way, and have different energy and different intermolecular forces.
Yes, atoms of different elements have a different number of protons.
Yes, atoms of different elements have a different number of protons.
no
Isotopes are atoms of the same element with different numbers of neutrons in their nuclei, resulting in different atomic masses. This is how there can be two different atoms of iridium.
who said this atoms of different elements are different
Molecule and compound comprises of different atoms. Atoms are combined in fixed ratio.
When a hydrate loses its water molecules, it is called an anhydrate.
No different ones, just Oxygen atoms.
