That includes carbon. Combining cations and anions to form binary inorganic compounds is simple. Is the nitrogen ion a cation or an anion? Nitrogen doesn't start out as a cation/anion, but it is in group 5A, so it has five valence electrons. Anonymous. Examples include the name of water, H 2 O, which is dihydrogen monoxide, and the name of NO, which is nitrogen dioxide. Update 2: THANKS!!!!! 7 Answers. From this fact it is apparent that most of the space of a crystal is occupied by the anion and that the cations fit into the spaces between them." The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride. You can often […] NH 3 is a neutral molecule, in this one nitrogen atom is covalently bonded to three hydrogen atoms. A metal reacts with a nonmetal to form an ionic bond. When nonmetal atoms gain electrons, they often do so until their outermost principal energy level achieves an octet. The ammonium ion is a postively charged ion or cation and has the chemical formula, NH 4 + No element is a cation or an anion. therefore a charge of -3. NH4+ is an ion (or cation, called ammonium) that can form compounds, and contains the elements N (nitrogen) and H (hydrogen). The same prefixes are applied to indicate the quantities of cation or anion atoms. The rules for naming and writing the formulas of organic compounds … Cations and Anions in Organic Compounds . However, nitrogen has two nonbonded electron pairs on it that can attach to a hydrogen ion (H+). All of these anions are isoelectronic with each other and with neon. It is formed when a proton is added to the compound ammonia, NH3. Favorite Answer. Relevance. To become stable (have a complete octet), it either has to lose five electrons or gain three. This process is illustrated below for the elements fluorine, oxygen, and nitrogen. Anions are the negative ions formed from the gain of one or more electrons. But most anions are large, as is the most common Earth anion, oxygen. Some may become ions through chemical reactions. Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. To find out what charge an element will be look at its group number: N is group 5, so it will gain 3 electrons to complete its electron shell. 1 decade ago. This entire charge cluster is called the ammonium ion, and it IS a cation. So NH3 combines with H+ to give NH4+. Answer Save. Cations and anions are measured by their ionic radius and they differ in relative size: "Cations are small, most of them less than 10 −10 m (10 −8 cm) in radius.
