we know 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.
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.
Metals tend to form cations, or ions with a positive charge. Nonmetals tend to form anions, or ions with a negative charge. Remember that ions form to put the element in noble gas configuration with 8 valence electrons. Elements forming ions will take the most direct addition or subtraction of electrons to achieve this.
An element's number of protons can predict whether it will form a cation or anion. It will form a cation if it has more protons than electrons, or an anion if there are more electrons than protons.
An anion is a negatively charged ion. A cation is a positively charged ion.Anion gets its name from the fact that anions migrate to the anode (positively charged electrode). Cation gets its name because cations migrate to the cathode (negatively charged electrode). Note, therefore, that the charge on the ion is opposite the charge of the electrode toward which it migrates. (Positive attracts negative and negative attracts positive).
Ions are the formation of unbalanced atoms due to an attraction caused by a near completion of an electron ring in one atom and extra or valence electrons in the outer ring of another. If an atom gains an extra electron its over all charge is negative and the opposite is true for the atom gaining an electron.

cations, positively charged ions, can be told from anions, negatively charged ions, bysize--cations are smaller then the average atomic mass of the element --anions are largertype--cations are made from metals --anions are non-metalsorder--cations are always listed first in a chemical equation
Cations are formed by the loss of electrons, anions are formed by the gain of electrons. The force of attraction between cations and anions results in ionic bond.
The attractions between anions and cations in a crystal are known as ionic bonds. These bonds are formed due to the electrostatic attraction between the positively charged cations and the negatively charged anions.
Cations and anions are formed through the process of ionization, which involves the gain or loss of electrons by atoms. In Telugu, cations are known as "క్యాటియన్లు" (Kyaṭiyannlu), which are positively charged ions formed by losing electrons. Anions, on the other hand, are called "ఆనియన్లు" (Āniyannlu) and are negatively charged ions formed by gaining electrons.
Cations are formed if electrons are less. Anions are formed if electrons are more.
Cations are positively charged ions that are formed by losing electrons, while anions are negatively charged ions that are formed by gaining electrons. Cations tend to be metals, while anions tend to be nonmetals.
Cations are formed when atoms lose electrons and hence are smaller in size than the corresponding atoms. Anions are formed when atoms gain electrons and hence are larger in size than the corresponding atoms.
Yes. Anions are negative ions and cations are positive ions.
The ions are b, anions and cations. Note that xenon is not an ion, it is a noble gas.
Yes, anions have a larger radius compared to cations.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
