Anion and cation

Answer 1

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 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.

Answer 2

anion negatively charged atom

cation positively charged atom

Answer 3

Anion is a negative charge ion.

Cation is a positive charge ion.
