Scientists don't believe atoms exist- they know atoms exist. No matter what type of field they study, the 'theory' of the atom explains many things about matter and chemistry and what make things happend in the physical world.
because they are the basic building blocks of everything.
because scientists say so.Literally speaking, scientists will use various magnifying devices, such as microscopes, to view very small structures like atoms.
oxygen atoms
We wouldn't know because if space didn't exist earth wouldn't exist and if earth didn't exist we wouldn't exist! So there you go there is your answer.
Rainbows do exist, yes.
fusion of hydrogen atoms into helium atoms
He does exist like God
Yes: Atoms of krypton almost always do exist independently of chemical bonding to any other atoms.
Atoms cannot exist in a free state on their own, but can exist in a free state as molecules.
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
ATOMS are real life examples of atoms. They do exist.
The were not invented, they exist. Atoms and molecules were discovered.
That they exist.
everywhere there is matter
Atoms had to be the very first creation in order for anything to exist.
Hydrogen exist as H2.It has 2 atoms in a molecule.
No.
molecules
I think Democritus first posited the existence of atoms.
