Question

Explain cation and anion

Answer 1

A cation is an ionic species with a positive charge. The word "cation" comes from the Greek word "kato," which means "down." A cation has more protons than electrons, giving it a net positive charge. ... The symbol for a cation is the element symbol or molecular formula, followed by a superscript of the charge

An anion is an ionic species having a negative charge. The chemical species may be a single atom or a group of atoms. An anion is attracted to the anode in electrolysis. Anions are typically larger than cations (positively charged ions) because they have extra electrons around them

Answer 2

Anion a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis. An anion is an ionic species having a negative charge. The chemical species may be a single atom or a group of atoms. An anion is attracted to the anode in electrolysis. Anions are typically larger than cations (positively charged ions) because they have extra electrons around them.

for example

Chlorine gains one electron to form chloride ion(Cl-), as in NaCl. Flourine gains one electron to form flouride ion(F-)

Cation a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis. a cation is an ion, or charged particle, with a positive charge. In other words, a cation has more protons than electrons. If you come across the word ion in a chemistry or physics class, cation and anion won't be far behind.

for example

Na+, Mg2+, Al3+, NH4+ etc.They were are formed when a metal loses electrons and a nonmetal gains those electrons.
