H for hydrogen
calcium atoms, sodium, chlorine, and sulphur atoms
There are many examples of atom, 106 in fact. Look at the Periodic Table of the elements.
The movement of Atoms as they attract, move and repel.
Molecules are not atoms, so I assume they can be classified as non-examples of atoms. Water is a molecule, and therefore not an atom. Water is comprised of two hydrogen atoms and one oxygen atom. Carbon is an atom.
Some examples of a molecules is water, tables, people, and objects that basically are made up of atoms which make molecules.
some microscopic things could be molecules, atoms,and anything that you can see under a microscope
ATOMS are real life examples of atoms. They do exist.
Molecules with giant-covalent structures have thousands of atoms in them, and some examples include diamond, graphite, hydrocarbons with a relatively longer carbon chains, silica and carborundum.
Compound is made out of different types of atoms. Some of the examples are, H20, Co2, KMno4. Elements are made out of only the same atom.
Examples of molecules include water (H2O), carbon dioxide (CO2), and glucose (C6H12O6). Non-examples of molecules would be single atoms like helium (He) or ions like sodium (Na+).

Some examples of molecules that can act as both hydrogen bond donors and acceptors include water (H2O), ammonia (NH3), and ethanol (C2H5OH). These molecules have hydrogen atoms that can form hydrogen bonds with other molecules by donating or accepting hydrogen atoms.
