  2. Magnesium oxide - Wikipedia

    en.wikipedia.org/wiki/Magnesium_oxide

    Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding.

  3. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    The charge of the resulting ions is a major factor in the strength of ionic bonding, e.g. a salt C + A − is held together by electrostatic forces roughly four times weaker than C 2+ A 2− according to Coulomb's law, where C and A represent a generic cation and anion respectively. The sizes of the ions and the particular packing of the ...

  4. Periclase - Wikipedia

    en.wikipedia.org/wiki/Periclase

    Periclase is a magnesium mineral that occurs naturally in contact metamorphic rocks and is a major component of most basic refractory bricks. It is a cubic form of magnesium oxide (Mg O). In nature it usually forms a solid solution with wüstite (FeO) and is then referred to as ferropericlase or magnesiowüstite. [6]

  5. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    Forming an ionic bond, Li and F become Li + and F − ions. An ion (/ ˈ aɪ. ɒ n,-ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge ...

  6. Metallic bonding - Wikipedia

    en.wikipedia.org/wiki/Metallic_bonding

    In a sense, metallic bonding is not a 'new' type of bonding at all. It describes the bonding only as present in a chunk of condensed matter: be it crystalline solid, liquid, or even glass. Metallic vapors, in contrast, are often atomic or at times contain molecules, such as Na 2, held together by a more conventional covalent bond. This is why ...

    The internet is claiming that taking vitamin D and magnesium has a ton of benefits. Dietitians weigh in on if taking vitamin D and magnesium together is safe.

  8. Salt (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Salt_(chemistry)

    The constituent ions are held together by electrostatic forces termed ionic bonds. The component ions in a salt can be either inorganic, such as chloride (Cl −), or organic, such as acetate (CH 3 COO −). Each ion can be either monatomic (termed simple ion), such as sodium (Na +) and chloride (Cl −) in sodium chloride, or polyatomic, such ...
