Q

three physical properties of metal

A

metal atoms have a latice structure so the valence electron is able to move freely (metalic bonding)
metals conduct electricity because electrons are free to move
metals are malleable and ductile as atoms can slide alongside eachother without breaking the metalic bonds

Q

the more reactive a metal is the more easily it…..

A

loses outer valence electrons and forms postive cations

22
what does the the activity series do
arranges metals in order of chemical reactivity
23
most reactive to least reactive
Li,K,Na,Ca,Mg,Al,Zn,Fe,Sn,Pb,H,Cu,Ag,Au,Pt
24
Metals will react depending on
their postion in the activity series the lower the postion the less likely they are to react this is to do with the number of elecrtrons in the valance shell
25
applications of metal reactivity
what type of metal would you use for making an aroplane and why practical questions
26
metal + oxygen ---->
metal oxide
27
lithium Potassium and sodiums reaction with oxygen
react rapidly forming a powdery oxide does not protect metal MUST BE STORED IN OIL
28
lithium potassium and sodiums reaction with heat
reacts forming dangerous metal oxide
29
how does calcium react think about the activity series
burns with bright red light forming white powdery calcium oxide
30
how does magnesium react
burns with bright white light and forms a powdrey oxide
31
aluminium copper iron lead zinc react how with heat
same light reactions basically
32
word equation for metal and oxygen
metal + oxygen ---> metal oxide
33
word equation for water
metal + water ---> metal hydroxide + hydrogen
34
word equation for acid
metal + acid ---> salt + hydrogen
35
what metal is used for electrical wiring and why
copper because its high conductivity and its ductile
36
what metal is used for producing fishing sinkers and why
lead because its dense and malleable
37
what metal is used for making fence wire and why
iron because its hard and ductile
38
what metal is used for making jewellery and why
silver and gold because they are lustrous and non reactive
39
what metal is used for making planes and why
Aluminium because its malleable and low density
40
what is the definition of a displacement reaction
when a metal and an ionic solution reacts spontaneously and the metal and metal ion swap (displace)
41
what is the word equation for displacement reaction
A + BC ----> B + AC
42
allotropes of oxygen
ozone
43
3 allotropes of carbon
diamond, graphite, graphene
44
3 allotropes of sulfur
plastic sulfur, rombic sulfur, monoclinic sulfur
45
describe atomic structure of carbon
Carbon has an atomic number 6 this is because it has 6 protons, as its an atom it contains 6 electrons these are arranged in two electron shells. The first shell contains 2 electrons, while the valence shell contains 4 electrons.
46
describe atomic structure of oxygen
oxygen has an atomic number 8 this is because it has 8 protons, as its an atom it contains 8 electrons these are arranged in two electron shells. The first shell contains 2 electrons, while the valence shell contains 6 electrons.
47
describe atomic structure of sulfur
sulfur has an atomic number 16 this is because it has 16 protons, as its an atom it contains 16 electrons these are arranged in three electron shells. The first shell contains 2 electrons, while the second shell contains 8 electrons and valence shell contains 6.
48
describe atomic structure of chlorine
chlorine has an atomic number 17 this is because it has 17 protons, as its an atom it contains 17 electrons these are arranged in three electron shells. The first shell contains 2 electrons, while the second shell contains 8 electrons and valence shell contains 7.
49
what are three uses of oxygen
to remove impurites from iron aid to breathing in hospitals, mountaineering and deep sea diving. In rocket fuels for space travel.
50
what are three uses of nitrogen
food packaging so no crushing In large quantities to produce ammonia gas then used to make nitric acid, fertilisers, dyes and explosives. Liquid nitrogen to ‘burn off’ warts from the skin.
51
what are uses of chlorine
As a bleach in the pulp and paper industry, and textile industries. Treatment of sewage. As a strong bleach in cleaners such as Janola. To sterilise water in swimming or spa pools.
52
ionic bonds are...
metal and non metal bonding
53
why is an alloy harder then a non alloy metal
because it has different sizes of atoms forming it creating a bumpy lattice structure
54
first step in writing a balance symbol equation
write the equation in full form without adding any big numbers infront
