A single charged atom is called a simple ion I think as opposed to a group of ions or radicals.
A polyatomic ion.
Not simple to answer - acidic solutions contain more hydrogen ions that hydroxide ions, but there are very many ions that can cause hydrogen ions to be in excess - for instance the hydrogen-sulphate ion (from an acid salt such as sodium hydrogen-sulphate) when added to water has a tendancy to split into hydrogen and sulphate ions, so making the solution acidic. Not all acid salts are acid in soultion - for instance sodium hydrogen-carbonate is alkaline. When dissolved in water, the hydrogen-carbonate ion tends to react with hydrogen ions in the water to form molecular carbonic acid - removing hydrogen ions from the water and hence making it alkaline. Acid salts of strong acids, such as sulphuric, hydrochloric, nitric, are acidic in solution. Acid salts of weak acids, such as carbonic, sulphurous, are alkaline in solution. Just a few simple examples.
one OH- ion, and a H+ ion. (That's H20 when you put them together).
which element can only formed one ion
No No, sugar is not an ion. In fact, it doesnt even dissociate in water. It is a compound.
No. Sulfur can form an S2+ ion.
Au3+
Mg2+
Ac3+
The common simple ion is S-2 and the most common polyatomic ion is probably SO4-2.
Cl-.
it is very simple we add the numbers of protons with the numbers of neutrons and the result would be the weight of the ion
Negative 2.
It is polyatomic because it is composed of two oxygen atoms with a 2- charge, [O_O]2-.
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
Na+, but there is no such thing as NaCI, it is NaCl , simple table salt
Oxygen. Hydronium is simple H3O+
