Definition of ion in English: ionnoun ˈʌɪən An atom or molecule with a net electric charge due to the loss or gain of one or more electrons. See also cation, anion Example sentencesExamples - When he or she begins to perspire they will lose moisture as well electrolytes, or ions.
- The charge on the complex ion is the sum of the charges on the metal ion and the ligands.
- You can take away the electron and make an ion, but you can't take away any neutrons.
- At that stage, the electrons and ions combined into neutral atoms that no longer scattered the radiation.
- Some compounds have polyatomic ions, where the ion is composed of two or more atoms.
- The bacteria also release protons or hydrogen ions, which go into solution.
- Other atoms will shed or gain electrons, becoming electrically charged ions.
- The net charge on an ion is denoted by a superscript showing both the size and charge.
- The acidity of a substance is determined by how readily it donates hydrogen ions or protons.
- The methanol reacts with water in the presence of a catalyst to produce hydrogen ions and electrons.
- Like the Solar Wind, the magnetosphere is full of plasma, consisting of ions and electrons.
- Switching off the electric field allows the ions to drop onto the silicon, where they bond to the surface in this pattern.
- The ratio of ions in a formula unit depends on the charges of the ions in the compound.
- A buffer is a system of chemicals that combines with an excess of hydrogen ions or hydroxide ions.
- It creates electrically charged particles called corona ions which are carried away from the cable by the wind.
- He discovered that power lines produce electrically charged particles called corona ions.
- If just protons or sodium ions are present, the condition is not fulfilled and the logical molecule remains zeroed.
- The hydrogen cation, one of the most common ions in the universe, is just a lone proton.
- The reactant ions have enough energy to ionise the molecules of interest but not enough to break them up.
- Compounds that attach to metal ions by sharing their electrons are known as ligands.
