Year 8 Periodic Table

Question 1

Element

Answer 1

An element is a substance that is made up of only one type of atom.

Question 2

Group on the periodic table

Answer 2

A group is the rows on the table excluding the transition metals, lanthanides and actinides.

Question 3

Period

Answer 3

A period is the columns on the periodic table.

Question 4

Alkali metals

Answer 4

The alkali metals are all the metals in group 1

Question 5

Alkaline earth metal

Answer 5

Alkaline earth metals are all the metals in group 2

Question 6

Halogens

Answer 6

The halogens are all the gases in group 7

Question 7

Noble Gases

Answer 7

The noble gases are all the gases in group8/O

Question 8

Transition metals

Answer 8

The transition metals are the big block of metals in the centre in the table. They don’t follow a set pattern of how many electrons they have.

Question 9

Periodic Table

Answer 9

The Periodic table is a table that lists all of the known elements in various patterns e.g. the amount of electrons each element has.

Question 10

Metal + acid

Answer 10

Metal salt + hydrogen

Question 11

Nitric acid + calcium

Answer 11

Calcium nitrate + hydrogen

Question 12

Metal + water

Answer 12

Metal hydroxide + hydrogen gas

Question 13

Potassium + water

Answer 13

Potassium hydroxide + hydrogen gas

Question 14

Metal + oxygen

Answer 14

Metal oxide

Question 15

Silver + oxygen

Answer 15

Silver oxide

Question 16

Displacement reaction

Answer 16

A displacement reaction is when a metal compound gets the metal removed and another metal taking it’s place by a chemical reaction. In the reactivity series if a metal is stronger than the one in the compound it will replace it.

Question 17

Copper sulphate + magnesium

Answer 17

Magnesium sulphate + copper

Question 18

Zinc oxide + iron

Answer 18

No reaction

Question 19

Metal ore

Answer 19

A metal ore is a rock that contains metal. This metal can be extracted.

Question 20

How is metal extracted from an ore?

Answer 20

Metal is extracted by ores using heat. The ore is placed in a furnace and heated up. The metal sinks to the bottom and then falls through the grate.

Question 21

Thermite reaction

Answer 21

A thermite reaction is a displacement reaction where iron oxide i reduced and aluminium is oxidised. The reaction start to happen at around 1700°C so a magnesium ribbon is burned.

Question 22

Reactivity series

Answer 22

The reactivity series tells us the order in how reactive the metals are and some also tell us what the metals can react with, e.g. water, ixygen.

Question 23

What change could you see to the nail if the iron nail displaces copper in copper sulphate?

Answer 23

It would turn copper coloured, brown or pink.
