Ions chemistry notes
Webionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons … WebIonic Compounds (GCSE Chemistry) Ionic Structure . Ionic compounds are held together by ionic bonding. In an ionic compound there are strong electrostatic forces of attraction between oppositely charged ions, this is known as ionic bonding. These forces operate in all directions holding the oppositely charged ions together.; Ionic compounds form crystals …

WebNote the usefulness of the periodic table in predicting likely ion formation and charge (Figure 2.29). Moving from the far left to the right on the periodic table, main-group elements tend to form cations with a charge equal to the group number. That is, group 1 elements form 1+ ions; group 2 elements form 2+ ions, and so on. WebNOTE: When the concentration of ammonia is high (6M is used), two ammonia molecule can both share its lone pair of electrons to bond with the silver ion, forming a water-soluble complex ion. [H3N: -> Ag+ <- :NH3] As a result, the silver chloride precipitate dissolves which can be used as a confirmatory test for the silver ions.
