Question 0

Properties of Metals

Answer 0

• good conductors of electricity
• good conductors of heat
• malleable
• ductile
• high melting point
• solid at room temperature

Question 1

Isotopes

Answer 1

Atoms which have the same number of protons but not neutrons

Question 2

Metallic bonding

Answer 2

positive ions surrounded by delocalised electrons

• has a lattice
• electrostatic attractions

Question 3

Malleable and ductibility

Answer 3

• can apply force to the solid
• shape will hold as positive ions will slip
• the electrostatic forces and attractions are still present and will hold the new shape

Question 4

Alloys

Answer 4

• mixtures of metals

- creates new properties

Question 5

Ions

Answer 5

• electrically charged species formed when atoms gain or lose electrons

Question 6

cation

Answer 6

• positive, loses an electron

Question 7

anions

Answer 7

• negative

- gains
