Document Summary
Ions: elements that lose an electron, and those that gain an electron will react with each other by transfer of an electron. D. ions of some common elements: metals from cations. 2. reactive nonmetals form anions: noble gases are not reactive. Polyatomic ions: an ion composed of more than one atom, atoms in the ion are held together by covalent bonds, charge because the number of electron is not the same is the number of protons in the atoms. A. the electrical attractions between ions of the opposite charge. !1: compounds of this type are referred to as ionic compounds a) ionic solids: crystals in which ions are attracted by ionic bonds to their nearest neighbor. Wednesday, january 25, 2017 (1) held rigidly in place by attraction to their neighbors (2) ions in each compound settle in a pattern: formulas of ionic compounds.
