A molecule can be a repeat of the same atom, such as the oxygen molecules we breathe, or can be made up of a variety of atoms, such as a sugar molecule made of carbon, oxygen and hydrogen.

Atom vs Element vs Molecule vs Compound. The table below explains the differences between the atom, element, molecules and a compound. Check and clear all your doubts related to these four.

Replacing a single atom in a molecule without altering the others has always been a challenge for chemists. Now, a novel technique based on light simplifies this operation.

Using nuclear magnetic resonance, researchers at ETH Zurich have studied the atomic environments of single platinum atoms in ...

But with only 1 oxygen atom, a water molecule only has half of what is needed to make 1 molecule of oxygen gas. So, 2 water molecules will produce 2 molecules of hydrogen gas but only 1 molecule of ...

X-ray-excited electrons are then tunneled to the detector tip (gray) via overlapping atomic/molecular orbitals, which provide elemental and chemical information of the iron atom. Credit: Saw-Wai Hla ...

The water molecule has a total of 10 protons and 10 electrons (8 from the oxygen atom and 1 from each of the two hydrogen atoms). Since it has the same number of protons and electrons, the water ...
