1f ionic bonding

Question 1

what is an ion

Answer 1

Atoms​ ​that​ ​have​ ​lost​ ​or​ ​gained​ ​electron/electrons.

Question 2

what happens when a metal reacts with a non metal

Answer 2

​electrons​ ​in​ ​the​ ​outer​ ​shell​ ​of​ ​the​ ​metal​ ​atom
are​ ​transferred

Question 3

what is a cation

Answer 3

​positive​ ​ion​ ​(+​ ​→​ ​ca+ion)

Question 4

what is an anion

Answer 4

negative​ ​ion​ ​(Negative​ ​→​ ​aNion)

Question 5

know charges of all groups

Answer 5

● group​ ​1​ ​→​ ​+1
● group​ ​2​ ​→​ ​+2
● group​ ​3​ ​→​ ​+3
● group​ ​5​ ​→​ ​-3
● group​ ​6​ ​→​ ​-2
● group​ ​7​ ​→​ ​-1

Question 6

what is an ionic compound

Answer 6

.a giant structure of ions
.Held​ ​together​ ​by​ ​strong​ ​electrostatic​ ​forces​ ​of​ ​attraction​ ​between​ ​oppositely charged​ ​ions
.The​ ​forces​ ​act​ ​in​ ​all​ ​directions​ ​in​ ​the​ ​lattice,​ ​and​ ​this​ ​is​ ​called​ ​ionic​ ​bonding.

Question 7

why do compounds with giant ionic lattices have a high boiling point

Answer 7

Strong​ ​electrostatic​ ​forces​ ​of​ ​attraction​ ​between​ ​oppositely​ ​charged​ ​ions Require​ ​a​ ​lot​ ​of​ ​energy​ ​to​ ​overcome​ ​these​ ​forces​ ​of​ ​attraction Therefore,​ ​the​ ​compounds​ ​have​ ​high​ ​melting​ ​and​ ​boiling​ ​points

Question 8

when do ionic compounds conduct electricity

Answer 8

.As​ ​a​ ​solid,​ ​the​ ​ions​ ​are​ ​in​ ​fixed​ ​positions​ ​so​ ​can’t​ ​conduct​ ​electricity
.when​ ​molten​ ​or​ ​in​ ​aqueous​ ​solution​ ​the​ ​ions​ ​are​ ​free​ ​to​ ​move​ ​carrying​ ​charge and conducting​ ​electricity
