- The electronic configuration of many ions is that of the closest noble gas to them in the periodic table.
- An anion is an ion that has gained one or more electrons, acquiring a negative charge.
- A cation is an ion that has lost one or more electrons, gaining a positive charge.
How do you know if a compound is an anion or cation?
An anion is an ion that has gained one or more electrons , acquiring a negative charge. A cation is an ion that has lost one or more electrons, gaining a positive charge.
How will you be able to distinguish if the ion is a cation or anion based on the number of protons and number of electrons?
Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion . ... If the chemical species has more protons than electrons, it carries a net positive charge. If there are more electrons than protons, the species has a negative charge.
How do you tell if an ion is a cation?
- The electronic configuration of many ions is that of the closest noble gas to them in the periodic table.
- An anion is an ion that has gained one or more electrons, acquiring a negative charge.
- A cation is an ion that has lost one or more electrons, gaining a positive charge.
What is difference between cation and anion explain with example?
| Basis Anions Cations | Charge Type Negative Positive | Type of Element Non-Metal Metal | Type of Electrode used Anode Cathode |

What are examples of cation?
They are formed when a metal loses its electrons. They lose one or more than one electron and do not lose any protons. Therefore, they possess a net positive charge. Some examples of cations are Calcium (Ca 2 + ), Potassium (K + ), hydrogen (H + ).
Is Al a cation or anion?
| Species Name charge | Al + Aluminum atom cation 1 | Sc + Scandium cation 1 | Ga – Gallium atom anion -1 | Ga + Gallium atom cation 1 |

Is Potassium a cation or anion?
| Species Name charge | Na + Sodium atom cation 1 | K – Potassium atom anion -1 | K + Potassium atom cation 1 | Cu – Copper atom anion -1 |

Is phosphate a cation or anion?
The phosphate anion is actually a polyatomic ion made up of one phosphorus atom and four oxygen atoms. The chemical formula of the anion is PO3−4 . Now, ionic compounds are always neutral. This means that you must balance the 3− charge on the anion by using three potassium cations.
What is anion give example?
Anions are negatively charged ions. They are formed when non-metal gains the electrons. They gain one or more than one electron and do not lose any protons. ... Some examples of anions are Iodide (I – ), chlorine (Cl – ), hydroxide (OH – ) .
What do you mean by cation and anion?
Cations are positively-charged ions (atoms or groups of atoms that have more protons than electrons due to having lost one or more electrons). Anions are negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons).
What is the symbol of cation?
| Cations Anion | Symbol Name Symbol | H+ hydrogen ion H- | Li+ lithium ion F- | Na+ sodium ion Cl- |

Is a cation positive or negative?
Positively charged ions are called cations; negatively charged ions, anions.
How is cation formed explain with example?
Cations are the positive ions formed by the loss of one or more electrons . ... In this case, the magnesium atom loses its two valence electrons in order to achieve the same noble-gas configuration. The aluminum atom loses its three valence electrons.
Is Group 1 cation or anion?
Group I A (1) elements form cations with +1 charge . Group II A (2) elements form cations with +2 charge. Groups III B through II B (3 – 12) are transition metals. These elements form cations having varying amounts of charge.
Does magnesium form a cation or anion?
| Species Name charge | Mg + Magnesium atom cation 1 | Ca – Calcium atom anion -1 | Ca + Calcium atom cation 1 | Zn – Zinc atom anion -1 |
