Exempel på hur man kan använda ATOM i en mening

• For an ordinary atom which contains protons, neutrons and electrons, the sum of the atomic number Z and the neutron number N gives the atom's atomic mass number A.
• An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons.
• Of or relating to the atom, the smallest particle of a chemical element that retains its chemical properties.
• This comprises ions, neutral atoms and, unless otherwise stated, it can be assumed that the term atom includes ions.
• In this model, the electron cloud of an atom may be seen as being built up (in approximation) in an electron configuration that is a product of simpler hydrogen-like atomic orbitals.
• An alpha particle is identical to the nucleus of a helium-4 atom, which consists of two protons and two neutrons.
• The chemical notation for amines contain the letter "R", where "R" is not an element, but a "R-group" which means "rest of the molecule" and in amines could be a single hydrogen or carbon atom, or could be a hydrocarbon chain.
• Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom.
• For light atoms (Z<12), this energy is most often transferred to a valence electron which is subsequently ejected from the atom.
• determine the nature of one single atom seen on a metal surface and selected from neighboring atoms at the discretion of the observer”.
• 01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
• The term system here has a wide meaning; it can range from a collection of 'sufficient number' of atoms or a single atom to a macroscopic system such as a natural gas storage tank.
• A lactam is a cyclic amide, and beta-lactams are named so because the nitrogen atom is attached to the β-carbon atom relative to the carbonyl.
• In atomic physics, the Bohr model or Rutherford–Bohr model was the first successful model of the atom.
• It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms.
• Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor.
• Chemical affinity can also refer to the tendency of an atom or compound to combine by chemical reaction with atoms or compounds of unlike composition.
• A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.
• Ethers can again be classified into two varieties: if the organyl groups are the same on both sides of the oxygen atom, then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers.
• The higher the associated electronegativity, the more an atom or a substituent group attracts electrons.
