A monoatomic ion is one that forms from a single atom. Ions with a positive charge, such as sodium (Na+) are cations. Those with a negative charge, such as chlorine (Cl-) are anions. Monoatomic ions are also known as simple ions.Continue Reading
Ions form by gaining or losing electrons. In neutral atoms, the number of protons and electrons are equal. This gain or loss of electrons results in a positive or negative electrical charge. Ions form in several ways. Ionic compounds that dissolve in water dissociate into cations and anions while in solution. Ions form when atoms are bombarded with radiation. When certain ionic compounds melt, ions form in the liquid.
Substances that ionize in water are electrolytes. Pure water is a poor conductor of electricity. However, a water solution containing electrolytes conducts electricity. As the water evaporates, the ions join to form neutral compounds again. However, if other ions are present, they sometimes join to form new compounds. If an acid neutralizes a base, the H+ ions join the OH- ions to form water. The remaining ions form a salt. Certain ions combine in solution to form an insoluble material and precipitate out of the solution. In precipitation reactions, the ions not involved in the precipitate remain in solution.Learn more about Atoms & Molecules
An electrically charged atom is called an ion. Ions are formed when an atom either loses or gains an electron. Atoms tend to move toward a more stable electron configuration, which happens when an atom possesses an outer energy level filled with electrons.Full Answer >
In chemistry, "CN" refers to a carbon atom attached to a nitrogen atom with a triple bond to produce a cyanide ion. Although many compounds containing cyanide are extremely deadly and exist in the form of a colorless gas, some compounds are not dangerous and have practical applications.Full Answer >
The Lewis structure for the nitrate ion has a nitrogen atom in the center, with three oxygen atoms surrounding the nitrogen. There is one double nitrogen-oxygen bond and two single nitrogen-oxygen bonds. The nitrogen atom has no lone pairs of electrons.Full Answer >
A bicarbonate ion is a negatively charged molecule consisting of one carbon, three oxygen and one hydrogen atom. A bicarbonate ion is an intermediate product formed by the deprotonation of carbonic acid. Bicarbonate is very important to human health.Full Answer >
