Hmm... I'm pretty sure that all elements can form ions... But whether they contain ions, I'm very sure they don't.
A poliatomic ion contain two or more elements; for example (SO4)2 - contain oxygen and sulfur.
Hydrogen and oxygen are already elements. Elements do not contain other elements.
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
All inorganic salts are composed of a metal ion (or an ammonium ion) and an acid radical ion. Table salt for example is composed of a sodium ion and a chlorine ion (the radical ion of hydrochloric acid).Organic salts (called esters) may or may not contain a metal ion. Organic salts that do not contain a metal ion, its role is taken by an alkaloid radical ion.
No. Chloride is a negatively charge ion of chlorine. As chlorine is an element it does not contain any other elements.
Elements do not contain polyatomic ions. Examples of substances that do not contain polyatomic ions include water (H2O), sodium chloride (NaCl), and oxygen gas (O2).
A nitride contain the ion N3-, a sulphite contain the ion SO3-, a phosphate contain the ion (PO4)3-.
Potassium ion (K+) does not contain the element oxygen.
Sulfate minerals contain the sulfate ion (SO4) as their primary element. The sulfate ion consists of one sulfur atom bonded to four oxygen atoms. Some common sulfate minerals include gypsum, barite, and anhydrite.
All acids contain a hydrogen ion, H+. All bases contain a hydroxide ion, OH-
almost all but some cell does not contain sodium ion.
An acid contain the ion H+ or (COOH)+ and a base contain the ion (OH)-.
