  2. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  3. Caesium iodide - Wikipedia

    en.wikipedia.org/wiki/Caesium_iodide

    Caesium iodide or cesium iodide (chemical formula CsI) is the ionic compound of caesium and iodine. It is often used as the input phosphor of an X-ray image intensifier tube found in fluoroscopy equipment.

  4. Cerium - Wikipedia

    en.wikipedia.org/wiki/Cerium

    Cerium(IV) oxide ("ceria") has the fluorite structure, similarly to the dioxides of praseodymium and terbium. Ceria is a nonstoichiometric compound, meaning that the real formula is CeO 2−x, where x is about 0.2. Thus, the material is not perfectly described as Ce(IV). Ceria reduces to cerium(III) oxide with hydrogen gas. [25]

  5. Caesium phosphide - Wikipedia

    en.wikipedia.org/wiki/Caesium_phosphide

    Caesium phosphide refers to any of several inorganic compounds with the formula CsP x.The most studied member is Cs 3 P 7, [1] which forms yellow crystals of tetragonal structure (P4 1 group), [2] which turn brown when heated to 300 °C, and colorless when cooled with liquid nitrogen.

  6. Caesium bromide - Wikipedia

    en.wikipedia.org/wiki/Caesium_bromide

    Caesium bromide or cesium bromide is an ionic compound of caesium and bromine with the chemical formula CsBr. It is a white or transparent solid with melting point at 636 °C that readily dissolves in water.

  7. Radical (chemistry) - Wikipedia

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

    The hydroxyl radical, Lewis structure shown, contains one unpaired electron. Lewis dot structure of a Hydroxide ion compared to a hydroxyl radical. In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron.

  8. Isotopes of caesium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_caesium

    Caesium (55 Cs) has 41 known isotopes, the atomic masses of these isotopes range from 112 to 152. Only one isotope, 133 Cs, is stable. The longest-lived radioisotopes are 135 Cs with a half-life of 1.33 million years, 137

  9. Cubic crystal system - Wikipedia

    en.wikipedia.org/wiki/Cubic_crystal_system

    The structure can also be thought of as two separate simple cubic structures, one of each species, that are superimposed within each other. The corner of the chloride cube is the center of the caesium cube, and vice versa. [6] This graphic shows the interlocking simple cubic lattices of cesium and chlorine.
