- Presl also created naming conventions for oxides where the electronegative component of the compound became the noun, and the electropositive component became an adjective.
- It is likely that electropositive metals are ineffective for deliberately stimulated ( chummed ) sharks, competitively feeding sharks, and shark " frenzies ".
- When an electric field is applied to a copper wire, the conduction of electrons accelerates towards the electropositive end, thereby creating a current.
- The hybridisation of bond orbitals is determined by Bent's rule : " Atomic s character concentrates in orbitals directed toward electropositive substituents ".
- As an alternative to electrowinning, the wanted metal can be isolated by using a molten alloy of an electropositive metal and a less reactive metal.
- Electronegative substituents prefer to rotate outwards, to the same side as the R substituent on the nitrogen, whereas electropositive substituents prefer to rotate inwards.
- A hydroxide attached to a strongly electropositive center may itself ionize, liberating a hydrogen cation ( H + ), making the parent compound an acid.
- Menningococcal type IV pili bind DNA through the minor pilin ComP via an electropositive stripe that is predicted to be exposed on the filament's surface.
- For example, the electropositive metals or semimetals soluble in tin's solid phase e . g . antimony or bismuth, which prevent the decomposition.
- Most perchlorate compounds, especially salts of electropositive metals such as sodium perchlorate or potassium perchlorate, are inert and are slow to react with organic compounds.
- The key is that concentrating atomic s character in orbitals directed towards electropositive substituents is more favorable than removing s character from orbitals directed towards electronegative substituents.
- Unlike the other noble gases ( except possibly xenon and radon ), oganesson is predicted to be sufficiently electropositive to form an Og Cl bond with chlorine.
- It had been found that to strengthen the current, it was most advantageous to drive the northerly electropositive electrode deeper into the medium than the southerly electrode.
- Mike Rowe, from Discovery Channel s Dirty Jobs series, subsequently witnessed and participated in a test using an electropositive metal within 24 hours after the discovery.
- The last two species, especially the superoxide, are rare and are formed only in reaction with very electropositive metals; these species contain oxygen-oxygen bonds.
- When a highly electropositive metal is combined with a highly electronegative nonmetal, the extra electrons from the metal atoms are transferred to the electron-deficient nonmetal atoms.
- The X position is an electropositive cation ( such as an alkali metal ), while the A is a monovalent anion and the B is a divalent anion.
- Cesium, however, has the benefit of being the most " electropositive " element known to physics, as well as being oblivious to temperature or atmospheric conditions.
