(1) The net charge on an ion is denoted by a superscript showing both the size and charge.

(2) A sulphate ion

(3) Some compounds have polyatomic ions, where the ion is composed of two or more atoms.

(4) The charge on the complex ion is the sum of the charges on the metal ion and the ligands.

(5) You can take away the electron and make an ion , but you can't take away any neutrons.

(6) The bacteria also release protons or hydrogen ions , which go into solution.

(7) The ratio of ions in a formula unit depends on the charges of the ions in the compound.

(8) At that stage, the electrons and ions combined into neutral atoms that no longer scattered the radiation.

(9) The methanol reacts with water in the presence of a catalyst to produce hydrogen ions and electrons.

(10) Other atoms will shed or gain electrons, becoming electrically charged ions .

(11) When he or she begins to perspire they will lose moisture as well electrolytes, or ions .

(12) Switching off the electric field allows the ions to drop onto the silicon, where they bond to the surface in this pattern.

(13) Compounds that attach to metal ions by sharing their electrons are known as ligands.

(14) The reactant ions have enough energy to ionise the molecules of interest but not enough to break them up.

(15) He discovered that power lines produce electrically charged particles called corona ions .

(16) It creates electrically charged particles called corona ions which are carried away from the cable by the wind.

(17) A buffer is a system of chemicals that combines with an excess of hydrogen ions or hydroxide ions .

(18) Like the Solar Wind, the magnetosphere is full of plasma, consisting of ions and electrons.

(19) The hydrogen cation, one of the most common ions in the universe, is just a lone proton.

(20) The acidity of a substance is determined by how readily it donates hydrogen ions or protons.
