Cations and anions introduction: Ions which are a part of the science subject Chemistry forms from atoms and electrons that have either gained or lost their weight by the removal or adding of one or more valence electrons which would create either positive or a negative charge.
What are ions with negative charges called?
The ions with a negative charge are called anions and the ones with a positive charge are called cations. Since both of them have charges of opposing qualities, they get attracted to one another and thereby forming an ionic bond between them.
Which anions have a net negative charge?
Therefore, they possess a net negative charge. Some examples of anions are Iodide (I – ), chlorine (Cl – ), hydroxide (OH – ). When sodium a cation is depicted as Na +, the plus charge indicator shows that it has one electron less than the total number of protons.
Do cations lose 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 + ).
Quick summary
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). Cations are also called positive ions, and anions are also called negative ions.
What is a cation?
A cation is an ion with positive charge, which means it has more protons (positively-charged particles) than electrons (negatively-charged particles). Cations are formed when an atom loses one or more electrons: the loss of the negatively-charged electron (s) results in an overall positive charge.
What is an anion?
An anion is an ion with negative charge, meaning it has more electrons than protons. Anions are formed when an atom gains one or more electrons: the gain of the negatively-charged electron (s) results in an overall negative charge.
What is the difference between cations and anions?
The difference between cations and anions is, of course, their charge. But this difference in charge has an impact on how cations and anions behave and react.

How are cations and anions different?
The first difference is that anions possess negative electrical charges while the cations have positive electrical charges. Secondly, during electrolysis, anions move to the positive electrode which is referred to as the anode. However, the cations migrate to the negative electrode called cathode. Another difference between the two ions is that anions have more electrons than protons while the cations have more protons than electrons. Then there’s the difference that comes due to the etymology of the words. Anion comes from the Greek word “ano” which means “up.” On the contrary, the cation derives its meaning from a Greek word “kata” which means “down.” Finally, anions are non-metals while the cations are metals.

Which is larger, anions or cations?
Cations are smaller in size than anions. Anions are generally larger in size than cations. 7. Cations gain electrons and convert into neutral atoms or molecules. Anions generally lose electrons and convert into neutral atoms or molecules. 8. Cations form electrostatic or ionic bonds with anions to form ionic compounds.
What is the difference between an atom and an ion?
Ion can be defined as an atom or molecule that has a net electrical charge. In an atom the number of electrons and protons is equal so they possess zero charge or neutral in nature. While in ions the number of protons are equal but number of electrons are unequal. So, they possess either positive or negative charge.
What are ions with positive charge?
Those ions which possess positive charge are called cations. Na+, Al+3, Ce+3 etc. are examples of cations . When an atom loses its electron/s then it gains a positive charge due to less number of electrons than protons in its nucleus. Then this positively charged species is called cation.
What are negative charged ions?
Those ions which possess negative charge are called anions. O-2 , CN-, OH- , Cl- etc. are examples of anions. When an atom gains electron/s to get stability, then it gains a negative charge due to more number of electrons than protons in its nucleus. Then this negatively charged species is called anion.
What is a negatively charged particle called?
Then this negatively charged species is called anion. The term was coined by Faraday and Whewell. It is taken from the Greek word ἄνω ἰόv (anion) which means ‘going up’. S.No. Cation. Anion. 1. An ion or a charged particle which has a positive charge is called cation.
What are some examples of ions?
Na+, O-2, NH4+, OH- etc. are examples of ions. Ions which are a group of elements or atoms that are covalently bonded but carry either positive or negative charge are called polyatomic ions. CN-, OH-, NH4+, NO3-, CO3-2 etc. are examples of polyatomic ions.
Who invented the term "ion"?
The term ‘ion’ was 1st used by English physicist and chemist Michael Faraday in 1834 after a suggestion by English Polymath, Scientist, William Whewell. Michael Faraday used this term for those species which were moving one electrode to another through aqueous medium.
What is the difference between anion and cation resin?
