Cations have a positive charge. Typical cations include sodium (Na+), calcium (Ca++ = Ca2+), and magnesium (Mg++ = Mg2+ ). Anions have a negative charge. Typical anions include chloride (Cl-), sulfates (SO4 — = SO42–), and bicarbonates (HCO3-).

Which element is a cation?
If a metal element forms an ion, it always forms a cation. Some metals always form the same type of cation. For example, sodium always forms a +1 cation and magnesium always forms a +2 cation.

Is hydrogen a cation or anion?
One example is hydrogen, which may gain (H–) or lose (H+) an electron, forming hydride compounds such as ZnH2 (where it is an anion) and hydron compounds such as H2O (where it is a cation).
What are some examples of cations?
Examples of cations include the following:
- Calcium: Ca. 2+
- Silver: Ag. +
- Aluminum: Al. 3+
- Hydronium ion: H3O. +
- Ammonium: ion NH. 4+
- Mercurous ion: Hg. 2+2
- Ferrous Ion: Fe. +2
- Ferric Ion: Fe. +3
Is Zn a cation?
Zinc(2+) is a divalent metal cation, a zinc cation and a monoatomic dication. It has a role as a human metabolite and a cofactor.

What type of cation is zinc?
Zn2+
Zinc is a group 12 metal with an electron configuration of [Ar]3d104s2. Loss of the outer shell 4s electrons yields a bare divalent zinc cation (Zn2+) with the electronic configuration [Ar]3d10.
Is chloride an anion?
The chloride ion /ˈklɔːraɪd/ is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.
What is SO4 2 called?

- Calcium Ca+2. Iron Fe+3.
How do you find cations?
You can often determine the charge an ion normally has by the element’s 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.
Which elements do not form cations?
Helium and the other elements in its column are very unreactive. They don’t ever form anions or cations.
How do you write cations?
1. Write the symbol and charge of the cation (metal) first and the anion (nonmetal) second. 2. Transpose only the number of the positive charge to become the subscript of the anion and the number only of the negative charge to become the subscript of the cation.
Is a hydrogen a cation?
Hydrogen forms the only cation that has no electrons, but even cations that (unlike hydrogen) still retain one or more electrons are still smaller than the neutral atoms or molecules from which they are derived.
Is hydrogen H2 or H?
Hydrogen has a molar mass of 1 and it’s molecular formula is H2. Hydrogen, H, is the lightest element with the atomic number 1. It is a colorless, odorless, tasteless, and highly flammable gas with the molecular formula H2.
Is hydrogen a anion?
The hydrogen anion, H−, is a negative ion of hydrogen, that is, a hydrogen atom that has captured an extra electron. The hydrogen anion is an important constituent of the atmosphere of stars, such as the Sun.

What are Type 2 cations?
Naming compound with type II cations-type II cations are capable of having several charges. If the cation is not from group 1 or 2, or is not Ag+,Cd2+, Zn2+, or Al3+ then assume the cation is a type II cation. The cation is named first and the charge of the cation is expressed as a Roman numeral.
Which species is a cation?
ionic species
A cation is an ionic species with a positive charge. The word “cation” comes from the Greek word “kato,” which means “down.” A cation has more protons than electrons, giving it a net positive charge.
What are metal cations?
A metal ion is a type of atom compound that has an electric charge. Such atoms willingly lose electrons in order to build positive ions called cations.
