Additionally what is an example of a cation. Alkali metals and alkaline earth metals always form cations.
You can often determine the charge an ion normally has by the elements position on the periodic table.
Cations and anions periodic table. It can be possible to predict whether an atom will form a cation or an anion based on its position on the periodic table. Halogens always form anions alkali metals and alkaline earth metals always form cations. Most other metals form cations eg.
Iron silver nickel whilst most other nonmetals typically form anions eg. Cations positively-charged ions and anions negatively-charged ions are formed when a metal loses electrons and a nonmetal gains those electrons. The alkali metals the IA elements lose a single electron to form a cation with a 1 charge.

A cation is an ion that has lost one or more electrons gaining a positive charge. The first table hows the family element and ion name for some common monoatomic one atom cations. The second table gives the same information for some common monoatomic anions.
Some Common Monoatomic Cations. Sometimes you can predict whether an atom will form a cation or an anion based on its position on the periodic table. Alkali metals and alkaline earth metals always form cations.
Halogens always form anions. Most other nonmetals typically form anions eg. Oxygen nitrogen sulfur while most metals form cations eg.
Anions 1-acetate C 2 H 3 O 2-cyanide CN-amide NH 2-cyanate OCN-hydrogen carbonate fluoride F-bicarbonate HCO 3-hydride H-hydrogen sulfate hydroxide OH-bisulfate HSO 4-hypochlorite ClO-bisulfide HS-iodate IO 3-bisulfite HSO 3-iodide I-. Cations are ions which have a positive electrical charge. A cation has fewer electrons than protons.
An ion may consist of a single atom of an element a monatomic ion or monatomic cation or anion or of several atoms that are bonded together a polyatomic ion or polyatomic cation or anion. Because of their net electrical charge cations are repelled by other cations and are attracted to anions. In other words write the cation on the left and the anion on the right.
The formula of a salt is. Cation m anion n H 2 O. Where the H 2 O is omitted if the is zero m is the oxidation state of the anion and n is the oxidation state of the anion.
If m or n is 1 then no subscript is written in the formula. Use the periodic table to predict the charge an atom will have when it becomes an ion. Learn whether an ion is a cation or anion and how to write the formula depending on what charge the ion has.
Fei2 cation and anion About. You can often determine the charge an ion normally has by the elements position on the periodic table. The alkali metals the IA elements lose a single electron to form a cation with a 1 charge.
The alkaline earth metals IIA elements lose two electrons to form a 2 cation. Additionally what is an example of a cation. Positively charged ions are also called cation while negatively charged ions are called anions The position and groupings of elements in the periodic table are helpful when identifying the atoms that are most likely to form ions as well as whether or not those ions will be cations or anions.

Naming anions is slightly different than naming cations. The ending of the elements name is dropped and replaced with the -ide suffix. For example ceF- is the fluoride ion while ceO2- is the oxide ion.

A typical periodic table is shown here. As you can see the elements in the table are arranged by atomic mass from lowest mass in the upper left to highest on the bottom right.
Note that there is a placeholder after barium Ba for the lanthanide elements with atomic mass 57-70 and another placeholder after radium Ra for the actinide elements with atomic mass 89-102.
