Periodic Table

Question 1

What is a compound

Answer 1

• Compounds form when substances react together
• Compounds always contain one or more different atoms/elements
• Compounds always have a formula and combine in fixed ratios

Question 2

What is an element

Answer 2

• An element is something that cannot be broken down into anything simpler
• All elements are made up of one type of atom
• All the atoms in an element are the same as each other

Question 3

Atom Identity

Answer 3

• Each element has a different number of protons( positive particles) in the nucleus and we call this the PROTON NUMBER
• The modern periodic table uses this to order the elements

Question 4

Which element has 9 protons

Answer 4

Flourine

Question 5

Which element has a mass of 12

Answer 5

Carbon

Question 6

How many protons does chlorine have

Answer 6

17

Question 7

How many protons does sodium have

Answer 7

11

Question 8

properties of a typical metal when solid

Answer 8

good conducter of electricity
good conducter of heat
shiny
heavy
typically malleable and ductile
sonorous

Question 9

malleable

Answer 9

able to be hammered and pressed into shape without breaking or cracking

Question 10

ductile

Answer 10

able to be drawn out into a thin wire.

Question 11

properties of a typical non-metal

Answer 11

poor conducter of electricity and heat
dull
light
typically not malleable or ductile
not usually sonorous

Question 12

Reactions of metal

Answer 12

• metals will react with non-metals to form compounds
  e.g. Magnesium + oxygen = magnesium oxide
• ## Metal oxides will neutralise an acid BUT metals will not react together they will only mix together

Question 13

Reactions of non-metal

Answer 13

• Non-metals will react with both metals and non-metals
  e. g. Sulfur + oxygen = sulfur dioxide
• Non-metal oxides are often gases and when dissolved is acidic

Question 14

Periods

Answer 14

the horizontal rows of the periodic table are known as ‘periods’

Question 15

Groups

Answer 15

-elements are arranged in columns because their physical and chemical properties are similar and follow a pattern

Question 16

Group 1 =

Answer 16

the alkali metals

Question 17

Group 2 =

Answer 17

the alkali earth metals

Question 18

group 7 =

Answer 18

the halogens

Question 19

Group 0 ( 8 or sometimes 18 )

Answer 19

the noble gases

Question 20

Group 1

Answer 20

• group 1 alkali metals are not like most metals
• they are soft and have relativley low melting and boling points
• they are also very recative

Question 21

reactions of Group 1 metals with water

Answer 21

when we react alkali metals with water, we always produce an alkaline solution and hydrogen

Question 22

the word equation for lithium and water

Answer 22

lithium + water = lithium hydroxide + hydrogen
