C:2 Bonding,Structure and Properties of Matter Paper 1

Question 1

Name the 3 different types of bonding?

Answer 1

• 1) Ionic - Metals and non-metals
• 2) Covalent - non-metals and non-metals
• 3) Metallic - metals and metals

Question 2

What happens to the particles in Ionic bonding?

Answer 2

• In ionic bonding the particles are oppositely charged ions.

Question 3

What happens to the particles in Covalent bonding?

Answer 3

• In covalent bonding particles are atoms which share pairs of electrons.

Question 4

What happens to the particles in Metallic bonding?

Answer 4

• In metallic bonding the particles are atoms which Share Delocalised electrons.

Question 5

What Do electrons do in ionic bonding and what do non-metal atoms gain?

Answer 5

• Metal atoms lose electrons to become positively charged ions.
• Non metal atoms gain electrons to become negatively charged ions.

Question 6

which group are the ions produced by and what’s holding them the ionic compound together?

Answer 6

• The ions produced by metals in group 1 and 2 and by non-metal in group 6 and 7.
• Iconic Compounds are held by Strong electrostatic Forces.

Question 7

Name a Type of Substance Covalent Bonds can make?

Answer 7

• Covalent bonding can make simple molecular substances.
• Which are small molecules which the atoms in the molecular are joined by really strong covalent bonds But have interlocular forces between them.

Question 8

Name the 4 Properties of Simple molecules?

Answer 8

• 1) Low melting and boiling point - dues to weak intermolecular forces.
• 2) Don’t conduct electricity - no free electrons and ions.
• 3) often gases or liquids at room temp.
• 4) some dissolve in water.
