Ions are electrically charged particles. They form when an atom contains an unequal number of protons in the nucleus and electrons in the electron cloud. Of course, there should be neutrons in the nucleus too but that makes no difference since neutrons are neither -1e or +1e but are electrically neutral.Since protons are positively charged and electrons are negatively charged, if there are more electrons than protons, the atom or molecule will be negatively charged. This is called an anion.Conversely, if there are more protons than electrons, the atom or molecule will be positively charged. This is called a cation. GOOD LUCK.
examples include: hydroxide ions carbonate ions nitrate ions Sulphate ions Hydrogen Carbonate ions
Ions have a non-zero charge.Positive ions have a positive charge. Negative ions have a negative charge.
As the concentration of hydronium ions (H+ ions) increases or as the concentration of hydroxyl ions (OH- ions) decreases, the pH of the solution decreases

In an acidic solution chromate ions are converted into dichromate ions.
Spectator ions are ions that do not part in a chemical reaction.
Binary ions are ions that have one charge Multivalent ions have more than one charge polyatomic ions are ions with a covalent bond
Cations -- which are positive ions -- and anions, which are negative ions.
Positive ions are called - Cations Negative ions are called - Anions
acid produces H+ ions base produces OH- ions
yes positive ions are faster then negative ions
The pH of a solution is related directly to its concentrations of hydronium ions(H3O^+) and hydroxide ions(OH-). Acidic solutions have more hydronium ions than hydroxide ions. Neutral solutions have equal numbers of the 2 ions. Basic solutions have more hydroxide ions than hydronium ions.
An acidic solution has a greater number of hydrogen ions than hydroxide ions. However, technically they are hydronium ions (H3O+), not hydrogen ions.
In a slat positive ions and negative ions. In common salt, sodium chloride, sodium ions, Na+ and chloride ions Cl-
These ions are Na+ and OH-.
Ions exist in water solutions of ionic compouds. Cations are positive ions and anions are negative ions.
For example no3 or co3 are all polyatomic ions
Water is also unique in that it is both an acid (with H+ ions) and a lye (with OH- ions). It is thus both acidic and basic (alkaline) at the same time, causing it to be strictly neutral as the number of H+ ions equals that of the OH- ions. Because of its strong cohesion, only few water molecules dissociate (split) in their constituent ions: hydrogen ions (H+) and hydroxyl ions (OH-). Chemists would insist that H+ ions are really H3O+ ions or hydronium ions.
Acidic ions generally mean H+ ions. These are produced by acids in water. These ions get combined with water to form hydronium or H3O+ ions.
There are two types of ions in this compound, calcium ions and hydroxyl ions. The number of ions present in a sample can be calculated if the mass of the sample is known.
Sodium ions and potassium ions are pumped in opposite directions. Sodium ions are pumped out of the cell and potassium ions are pumped into the cell.
Ions are stable.
Strong bases dissociate entirely into metal ions and hydroxide ions.
