Bonding, Structure & Properties Of Matter

Question 1

Sublimation

Answer 1

When a solid turns straight into a gas

Question 2

Ionic lattice

Answer 2

The regular arrangement of ions in an ionic substance

Question 3

Electrostatic forces

Answer 3

The forces of attraction between particles with opposite charges
-holds together ionic lattices

Question 4

Properties of ionic compounds

Answer 4

• high melting and boiling points (solid at room temperature)
• conducts electricity when it has melted into a liquid or has been made an aqueous solution
• are insulators when solid

Question 5

Molecules

Answer 5

Two or more atoms held together by chemical bonds

Question 6

Properties of substance with small molecules

Answer 6

Low melting and boiling points, the intermolecular forces between small molecules are weak
Cannot conduct electricity as they have no charge

Question 7

Giant covalent structure

Answer 7

A structure were large numbers if atoms are joined together by covalent bonding

Question 8

Silicone dioxide

Answer 8

Example of a giant covalent structure

All atoms are linked together with strong covalent bonds

Question 9

Properties of giant covalent structures

Answer 9

High melting and boiling points

Most cannot conduct electricity, charged particles are not free too move
