TOPIC 1 - ionic bonding

what is ionic bonding

when atoms gain or lose electrons to form charged particls called ions

If an atom loses and electron it becomes a positive ion

If an atom gains an electron it becomes a negative ion

THE ELECTROSTATIC ATTRACTION BETWEEN POSITIVE AND NEGATIVE IONS

difference between ide and ate

ide is used for compounds that usually have a metal or non metal

ade is used for compounds containing a polyatomic ion with oxygen

what is the ion formula for hydroxide

OH-

what is the ion formula for nitrate

NO3-

what is an ion

an atom or group of atoms with a positive or negative charge

how are ionic compounds formed

they dont have an overall charge but are formed from positive or negative ions. they need to be balanced however

sulfate

SO4 2-

what is the ion formula for carbonate

CO3 2-

what is the ion formula for ammonium

NH4+

what is the structure of an ionic compound

attice structure

consisiting of a regular arrangment of ions

held together by strong electrostatic forces(ionic bonds) between oppositely charged ions
