types of substances

Question 1

what are ionic compounds are made up of

Answer 1

Ionic​ ​compounds​ ​are​ ​made​ ​up​ ​of​ ​a​ ​metal​ ​and​ ​a​ ​nonmetal

Question 2

what structures do ionic compounds have

Answer 2

Ionic​ ​compounds​ ​have​ ​regular​ ​structures​ ​which are giant​ ​ionic​ ​lattices

Question 3

what are within ionic compound sructures

Answer 3

strong​ ​electrostatic​ ​forces​ ​of​ ​attraction​ ​in​ ​all​ ​directions​ ​between​ ​oppositely charged​ ​ions.

Question 4

what are the melting and boiling points like of ionic compounds

Answer 4

They​ ​have​ ​​high​ ​melting​ ​and​ ​boiling​ ​points​,​ ​because​ ​a​ ​lot​ ​of​ ​energy​ ​is​ ​required​ ​to
break​ ​the​ ​many​ ​strong​ ​bonds

Question 5

do ionic compounds conduct electricity

Answer 5

When​ ​melted​ ​or​ ​dissolved​ ​in​ ​water,​ ​ionic​ ​compounds​ ​​conduct​ ​electricity​​ ​because
the​ ​ions​ ​are​ ​free​ ​to​ ​move​ ​and​ ​carry​ ​current,​ ​and​ ​they​ ​​do​ ​not​ ​conduct​ ​electricity as​ ​solids,​​ ​because​ ​the​ ​ions​ ​are​ ​fixed​ ​and​ ​are​ ​not​ ​able​ ​to​ ​move,​ ​carrying​ ​charge with​ ​them

Question 6

what do ionic compounds dissolve in water to form

Answer 6

ionic compounds often​ ​dissolve​ ​in​ ​water​​ ​to​ ​form​ ​an​ ​aqueous​ ​solution

Question 7

what states are substances of small molecules usually

Answer 7

gases or liquids

Question 8

what are the melting and boiling points like of simple molecular compounds

Answer 8

low boiling and melting points
