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.
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.
This is the ion Th4+
Gold forms a simple ion with a charge of +1.
Magnesium forms a simple ion with a 2+ charge, typically written as Mg2+.
Fluorine forms the fluoride ion, which has a charge of -1.
Ac3+
Sulfur commonly forms a -2 charge as a simple monatomic ion by gaining two electrons to achieve a stable electron configuration.
The common simple ion is S-2 and the most common polyatomic ion is probably SO4-2.
Na+, but there is no such thing as NaCI, it is NaCl , simple table salt
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.
Each hydrogen ion bonds with a water molecule (H2O) to form hydronium ions (H3O+). The hydrogen ion donates a proton to the oxygen atom in the water molecule, resulting in the formation of the hydronium ion.
No, CH4 (methane) is not a complex ion. A complex ion is a charged species formed from a central metal ion bonded to one or more surrounding ligands. methane is a simple covalent molecule composed of one carbon atom bonded to four hydrogen atoms.
No, oxide is just an oxygen ion. The formula is just O(-2 charge), hence not a polyatomic ion. Hydoxide on the other hand is a polyatomic ion, formula being OH(-1 charge)
