Flashcards in Chapter 1.4 Properties Deck (10)
1

Ionic compounds form a

lattice structure

2

An ionic lattice is a regular arrangement of

metal and non-metal ions

3

A lattice structure creates compounds with a

high melting point which conduct when molten or in solution.

4

Lattice structure compounds never conduct when

solid

5

Ionic compounds dissolve in water very

easily

6

When ionic compounds are dissolve their ions are

free to move and carry the electrical charge.

7

Covalent network substance have a

very high melting point and are very hard because of their strong bonds

8

Covalent molecules such as oxygen and water have

low melting and boiling points

9

Covalent compounds do not

conduct electricity except water.

10

EXCEPTION: Graphite is a covalent network that does conduct because

it has delocalised electrons
