Periodic Table

Question 1

Table of metal and non metal physical properties

Answer 1

Metal:                        
Lustrous
Hight Melting point
Malleable 
Ductile

Non Metal:
Non ductile
Brittle
Transparent thin sheet
Not sonorous/deep bell voice

Question 2

The physical properties of group 1

Answer 2

The lower down the more reactive they become . Their properties is that they are all reactive in a way

Question 3

What is a group

Answer 3

A group os an amount of elements with different chemical reactions

Question 4

What is a period

Answer 4

A period is the name given to a horizontal row of periodic table

Question 5

Describe the trend in period 2

Answer 5

The trend is that the higher you go the more reactive the elements become.
They could react in oxygen or in liquid

Question 6

Explain the chemical properties for group 1

Answer 6

All group 1 elements have exciting reaction with water. The reactions create hydrogen gas and also make alkalises. The reaction get more vigorous going down the group

Question 7

Describe the physical properties of group 7

Answer 7

They have both low boiling boiling points and melting points. The melting point and boiling point increases as you go down the group and their colours become darker.

Question 8

Describe the physical properties of group 0

Answer 8

They are very unreactive. From top to bottom they get slightly more reactive

Question 9

Explain the chemical properties of group 7

Answer 9

Like most non metals they do not conduct electricity and have low melting points. They act vigorously with chlorine which creates a bright flame

Question 10

What are displacement reactions in group 7?

Answer 10

A displacement reaction is when the more reactive element displaces the less reactive element.

Eg fluorine displaces bromine oxide= fluorine oxides+bromide
