Atoms are found joined together in independent particles called "molecules," as ions formed by the gain or loss of electrons from the atoms and as free atoms. Ions are held together in compounds by the attraction between the positive and the negative charges of cations and anions. 展开 ...
Ionic Bonds Ions have an electrical charge because they contain an unequal number of protons and electrons. An atom that has gained electrons is negatively charged (-). It has more electrons (-) than protons (+) An atom that has lost electrons is positively charged (+). It has more proto...
Chemical compounds contain at least two separate elements. Chemical compounds sometimes form when oppositely charged ions meet and bond together. Bonds Atoms are held together by nuclear and electromagnetic force. Separate atoms may share electrons to form covalent bonds as molecules. Of course, ionic...
Influence of the chemical state on the stopping of protons and He-ions in some oxides We present stopping cross section data of Al O and SiO for hydrogen- and helium-ions in the energy range 2-1000 keV, measured in transmission and in backsc... P Bauer,R Golser,D Semrad,... - 《...
Charge-exchange and proton-transfer reactions of theH 3O + ion with atoms and compounds of copper havebeen investigated in the burnt gases of premixed flames ofH 2+O 2+N 2 at atmospheric pressure. Theconcentrations of ions in these flames were determined using aquadrupole mass spectrometer. ...

In the trinuclear compound Ni 3( shi) 2( Hpko) 2( py) 2 (1), two metal ions show a square planar geometry while the third one is in an octahedral environment. The compounds with four and five nickel atoms construct metallacrown cores with two distinct connectivities. The tetranuclear ...
