Explanation:

An!ion is!a!small!particle!having!an!electrical!charge.!!Ions!are!either!single,

charged!atoms!(simple)ions),!or!small charged “molecules”!(polyatomic ions).!!

Examples!of!simple!ions!are Na+,!Ca+2,!ClE

,!and!SE2.!!Examples!of!polyatomic ions!are!

NH4

+ ,!CO3

!2 , and!OH! .!!Positively!charged!ions are!called!cations (pronounced!catE

eyeEons)!while!negatively!charged!ions are!called!anions (pronounced!anEeyeEons).!!

In!many!cases,!the!elements!position!on!the!periodic!table!will!help!you!determine!
