WebWater molecules (H 2 0) are very simple. They are made of two hydrogen (H) atoms bonded to one oxygen (O) atom. All water molecules are the same, but they are different from the molecules of any other substance. A water molecule is the smallest possible piece of water. You can break it up into smaller pieces, but they wouldn’t be water anymore. WebThe atoms in a molecule are always joined together by a covalent bond. ... Some electron microscopes can produce images of atoms and simple molecules. A water molecule, H 2 O, is about 0.3 nm ...

WebAtoms are held together by chemical bonds. Learn how atoms achieve a stable outer electron arrangement by bonding to each other in National 5 Chemistry. Web12 de abr. de 2024 · Nitrogen molecules are extremely stable, with their two nitrogen atoms held together by three strong covalent bonds. This stability is overcome in the Haber-Bosch process by combining nitrogen with hydrogen at around 400 o C and more than 150 atmospheres of pressure with the assistance of an iron-based catalyst. great depression hiding spots
