Ionic apps run with a mixture of native code and web code, providing full access to native functionality if necessary, with the bulk of the UI of the app built with standard web technology. Ionic utilizes native hardware acceleration features available in the browser (such as CSS animations) and optimizes rendering (avoiding expensive DOM ...
Open pages of the book Alice's Adventures in Wonderland, showing an ornate section break on the lower left page created from asterisks. It is used to signal a pause for the reader and a transition in the narrative. In books and documents, a section is a subdivision, especially of a chapter. [1] [2]
Gold pentafluoride, along with its derivative anion, AuF − 6, and its difluorine complex, gold heptafluoride, is the sole example of gold(V), the highest verified oxidation state. [ 18 ] Some gold compounds exhibit aurophilic bonding , which describes the tendency of gold ions to interact at distances that are too long to be a conventional Au ...
Ionic species: Atoms or molecules that have gained or lost electrons, resulting in a net electrical charge that can be either positively (cation) or negatively charged (anion). Species with an overall positive charge will be a cationic species. The sodium ion is an example of a cationic species and its formula is Na +.
For example, chemists often choose to look at a small space surrounding the nucleus of an atom: When an electrically neutral atom bonds chemically to another neutral atom that is more electronegative, its electrons are partially drawn away. This leaves the region about that atom's nucleus with a partial positive charge, and it creates a partial ...
Examples of Ionic volutes. From Julien David LeRoy, Les ruines plus beaux des monuments de la Grèce, Paris, 1758 (Plate XX) A volute is a spiral, scroll-like ornament that forms the basis of the Ionic order, found in the capital of the Ionic column. It was later incorporated into Corinthian order and Composite column capitals.
Nitrides of the group 7 and 8 transition metals tend to be nitrogen-poor, and decompose readily at elevated temperatures. For example, iron nitride, Fe 2 N decomposes at 200 °C. Platinum nitride and osmium nitride may contain N 2 units, and as such should not be called nitrides. [11] [12]
The strength of the M-O bond tends to increase with the charge and decrease as the size of the metal ion increases. In fact there is a very good linear correlation between hydration enthalpy and the ratio of charge squared to ionic radius, z 2 /r. [4] For ions in solution Shannon's "effective ionic radius" is the measure most often used. [5]
