atomic structure and bonding

Question 1

Define a covalent network

Answer 1

A 3 dimensional network of atoms joined together by strong covalent bonds

Question 2

Explain the high melting points of covalent network substances

Answer 2

Lots of energy is required to break the strong covalent bonds within the network

Question 3

Explain low melting and boiling points of covalent molecular substances

Answer 3

Forces of attraction are being broken, not the bonds

Question 4

Definition of an ionic bond

Answer 4

The electrostatic attraction between oppositly charged ions

Question 5

Describe the ionic compound structure

Answer 5

A lattice structure of oppositly charged ions with each positive ion surrounded by negative ions and vice verca

Question 6

What are ionic compounds made up of?

Answer 6

Metal and non metal ions joined together to form ionic bonds

Question 7

Non metal atoms join together to form covalent bonds

Question 8

During the conduction of an ionic solution of molten ionic compound ions move towards….

Answer 8

Oppositly charged electrodes in a process called electrolysis
