- DRutherford
5Tick all the boxes that contain general properties of metals.
- Adense
- Binsulator
- Cdull
- Dshiny
- Econductor
- Fmalleable
- Gbrittle
- Hductile
6Which part of the periodic table informs you how many electrons are in the outershell of any element?
- Amass number
- Bgroup number
- Catomic number
- Dperiod number
7Ionic bonds are formed of positive and negative ions that are held together by strong electrostatic forces of attraction
- ARichtig
- BFalsch
8Oxidation is [blank_start]loss[blank_end], Reduction is [blank_start]gain[blank_end]
Metals always form [blank_start]positive[blank_end] ions ([blank_start]oxidised[blank_end]/lose electrons).
A group 2 metal will form a positive [blank_start]ion[blank_end] (loses two [blank_start]electrons[blank_end]).
Non-metals form [blank_start]negative[blank_end] ions ([blank_start]reduced[blank_end]/gain electrons)- Aloss
- Bgain
- Cpositive
- Doxidised
- Eion
- Fatom
- Gcompound
- Helectrons
- Ineutrons
- Jprotons
- Knegative
- Lreduced
9Which of the following compounds are examples of covalent bonding?
- ADiamond
- BSodium chloride
- CWater
- DCarbon dioxide
- ADiamond
10Metallic bonding is made of positive ions that are held together by a “sea of [blank_start]delocalised[blank_end] electrons” from the outer shells of metal atoms.
The strong [blank_start]electrostatic[blank_end] forces between the ions and electrons mean metals have very high melting points.- Adelocalised
- Bdetached
- Cpositive
- Dmoving
- Eelectrostatic
- Fcovalent
- Gionic
- Hmetallic
11Giant covalent compounds are [blank_start]solid[blank_end] at room temperature. All of the atoms in a giant covalent structure are held together by strong [blank_start]covalent[blank_end] bonds. These bonds have to be broken, by large amounts of energy, to melt or boil these substances.
[blank_start]Diamond[blank_end] is made up of each carbon forming [blank_start]four[blank_end] covalent bonds.
[blank_start]Graphite[blank_end] is made of hexagonal rings of carbon, each atom forming [blank_start]three[blank_end] bonds. Each atom contributes [blank_start]an electron[blank_end] to the “sea of delocalised electrons”.- Asolid
- Bliquid
- Cgases
- Dcovalent
- Eionic
- Fmetallic
- GDiamond
- HGraphite
- Ithree
- Jone
- Kfour
- Ltwo
- Man electron
- Na proton
- Oa neutron
12Simple covalent compounds can conduct electricity.
- ARichtig
- BFalsch
13Calculate the formula mass of NaNO₃ (RAM Na=23, N=14, O=16)
- A113
- B159
- C85
- D53
14James burns 0.7 g of magnesium in air. What will be the most likely mass after heating?
- A0.0 g
- B0.7 g
- C0.76 g
- D0.64 g
15HCl is added to Mg in a flask. After 70 seconds all the hydrogen had been released, and there was no more Mg left. Which chemical was the limiting reactant?
- AHCl
- BMg
- CMagnesium chloride
- DHydrogen
16Fill the blank space to complete the text.
Calculate the relative formula mass of calcium hydroxide (RAM Ca=40, O=16, H=1): [blank_start]74[blank_end]
- A74
170.020 moles of calcium nitrate was dissolved in 160 ml of water. Calculate the concentration: [blank_start]0.125[blank_end] mol/dm3
- A0.125
18This equation is balanced.
- ARichtig
- BFalsch
19Balance the following equation (use the numbers 1, 2, or 3 to fill the blanks)
[blank_start]1[blank_end]N2 + [blank_start]3[blank_end]H2 --> [blank_start]2[blank_end]NH3
- A1
- B3
- C2
