This is an electrostatic attraction.
spectator ions
When a solution has more hydrogen ions it will be acidic.
Iodine has more radius. It has least attraction for electron.
Ions made up of more than one atom are called polyatomic ions.
Polyatomic ions.
If the solution is basic, there are more hydroxide ions than hydrogen ions. In an acidic solution, there are more hydrogen ions than hydroxide ions. The balance between these ions determines the pH of a solution.
These are called polyatomic ions.
Ions that consist of a single atom are called monatomic ions
Positive ions are called cations. These ions are formed when an atom loses one or more electrons, leading to a net positive charge. Cations are attracted to negatively charged ions (anions) to form stable compounds.
.... between one or more postive (metal) ions and one or more negative ions like chloride, sulfate, nitrate, carbonate etc. Example: 2Al3+ + 3SO42- --> Al2(SO4)3
Aluminum atoms are called ions, specifically aluminum ions. By losing their valence electrons, aluminum atoms become positively charged ions, as they have more protons than electrons.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
