CATIONS are POSITIVELY charged ions, whereas ANIONS are NEGATIVELY charged! Here's a trick: "That cool cat is giving off some real positive vibes..." So you easily know …"CATions" give off positive stuff. :) Or, you could think of it like this; cats have metal claws, and CATions are PAWSitive, so metals form positive cations. (MORE)
cations are positively charged ions that are produced when an atom loses electrons and anions are negatively charged ions that are produced when an atom gains electrons. we kn…ow that a atom needs 8 electrons in valance shell to or octet configuration ; duplet (2 electrons in outer most shell) , if an atom have atomic number 11 that is sodium and it can be written has 2,8,1 and it losses 1 electron to get duplet confg. as electrons are decreased they become positive ion or cations . anions are formed when number of electrons are increased by gaining electron to get given confg. ex: oxygen , atomic number 8 and written as 2,6 and it gains 2 electrons for octect confg.

A polyatomic ion is an ion containing two or more atoms, usually of more than one element. An example is the nitrate ion. (NOâ3 - ) This is 1 nitrogen with 3 oxygen's att…ached and bears a charge of 1-. The most common polyatomic ions are anions that contain oxygen attached to some other element called an oxoanion and are typically combinations of oxygen with a nonmetal. For a given nonmetal, there are often two or more common oxoanions SO 3 2- (sulfite ion) 1 sulfur 3 oxygens and a charge of 2-, (MORE)
Cations are the species that have net positive charge on them while anions are the species that have negative charge over them. For eg:-.
anions: SO 4 2- , CO 3 2- , S 2- ….
cations: Al 3+ , Sr 2+ , Ca 2+ (MORE)
An anion is a negatively charged ion with too many electrons, and is attracted to the anode while doing electrolysis\nA cation is a positively charged ion with too little elec…trons, and is attracted to the cathode while doing electrolysis When an atom loses one or more electrons, it then has more protonsthan electrons, and it becomes positively charged ion. Positivelycharged ion are called cations. Anion are negatively charged ions. periodic table consists of 8 groups. group I II III & IV are positively charged atoms while V VI& VII are negatively charged. so we can say that elements of group I, II, III & IV arecations and elements of group VI VII & VIII are anions (group VIII is also known as group 0 because its valance shell isalready complete and it does not have ability to loose or gainelectrons so it does not form ions which tells us that the elementsof this group are not included in neither cations, nor anions) (MORE)
Surfactants that comprise of organic compounds are amphiphilic, andform hydrophilic and hydrophobic groups when dissolved in aqueoussolution. Surfactants with negatively charg…ed and neutralhydrophilic groups are anionic and nonionic respectively. (MORE)
An ion is an atom which is not neutral i.e. it has excess of charge on it. There are two types of ions: .
Cation :- These have positive charge on them. They are formed whe…n an loses electrons and protons exceed their number. .
Anion :- These have negative charge in them. They are formed when an atom gains electrons and no. of electrons exceed the no. of protons. (MORE)
Cations are positively charged. Anions are negatively charged. Cations are smaller than the nucleus from which they are formed, and Anions are bigger than the nucleus from whi…ch they are formed. (MORE)
Anions are negative ions, so any element that gains a negative charge in a chemical reaction. Some examples of elements that commonly do this are the halogens (flourine, chlor…ine, bromine, iodine, astatine) and oxygen. (MORE)
No, cations have a positive charge and have lost electrons. Anions have a negative charge and have gained electrons. In an ionic compound anions and cations attract each other… due to opposite charges. (MORE)
An anion is anything with a positive charge. So an atomic anionmust be a positively charged atom. Atoms can only gain or loseelectrons, which are negatively charged. By losing… one or morenegative charges, which is to say electrons, an atom becomespositively charged since the protons in its nucleus are no longerbalanced by the lost electrons. So overall, an atomic anion is an atom that has given up one ormore electrons. (MORE)
