Atom - Electrons, Nucleus, Bonds: Once the way atoms are put together is understood, the question of how they interact with each other can be addressed—in particular, how they form bonds to create molecules and macroscopic materials. There are three basic ways that the outer electrons of atoms can form bonds: The first way gives rise to what is called an ionic bond. Consider as an example an ...
Chemical bonding - Visualization, Atoms, Molecules: The last opposition to the existence of atoms vanished in the early 20th century when techniques were developed that portrayed visual representations of atoms. The first such techniques made use of the diffraction of X-rays, where the pattern of interference between rays that are reflected by a crystal can be interpreted in terms of the ...
ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in ...
