How are elements arranged in the Periodic Table?
In rows called columns, by increasing mass number.
In rows called periods, by increasing mass number.
In rows called columns, by increasing atomic number.
In rows called periods, by increasing atomic number.
The electronic configuration of oxygen is:
2.4
2.6
1.2.4
2.8
Mendeleev’s Periodic Table was revolutionary because:
He ordered elements by both their properties and their atomic number.
He left gaps for undiscovered elements.
He used his Periodic Table to make predictions about undiscovered elements.
He ordered elements by both their properties and their atomic mass.

Similar reactivity
The same melting and boiling points
The same number of outer shell electrons
The same mass
Select the correct physical properties of the alkali metals from the list below.
Soft
Brittle
Dense
Have relatively low melting points
When lithium reacts with water, the following observations are true:
Melts into a ball.
Effervescence is seen.
Burns with a lilac flame.
Floats on the surface of the water.
When potassium reacts with water, the following observations are true:
Melts into a ball.
Effervescence is seen.
Burns with a lilac flame.
Floats on the surface of the water.
Why do the alkali metals get more reactive down the group?
They have smaller atomic radiI and less electron shielding.
They have greater atomic radii and more electron shielding.
It is easier for them to lose their outer shell electron.
The attraction from the nucleus for the outer shell electron is less.
Select the statements about the appearances of the halogens at room temperature and pressure which are true.
Chlorine is a purple gas.
Iodine is a grey solid.
Fluorine is a green gas.
Bromine is a red-brown liquid.
How should you test for chlorine gas?
Damp blue litmus paper goes red.
Damp red litmus paper goes blue.
Damp blue litmus paper goes red then bleaches white.
Damp red litmus paper goes blue, then bleaches white.
Select the correct equation from the options below:
Cl +H → HCl
Cl2 +H2 → 2HCl
Cl2 + H2 → HCl
2Cl +H2 → 2HCl
Reduction is:
Gain of oxygen
Loss of oxygen
Gain of electrons
Loss of electrons.
Oxidation is:
Gain of oxygen
Loss of oxygen
Gain of electrons
Loss of electrons
Select the correct ionic equation from the list below:
I− +Cl2 → Cl− +I2
I− +Cl → Cl− +I
2I− +Cl2 → 2Cl− +I2
2Cl− +I2 → Cl2 +2I−
Halogens are less reactive down the group because:
It is harder to gain an electron.
They have less shielding and smaller radii.
They have more shielding and larger radii.
The attraction of the nucleus to the electron to be gained is weaker.
Why are the noble gases unreactive?
They are already in molecules.
They have done all their bonding.
They have full outer electron shells.
They are colourless.
Noble gases are useful for different applications because:
They are inert.
They are very reactive.
They have a low density.
They are not flammable.
Select the correct properties of transition metals from the list below:
They tend to form coloured compounds.
They are good catalysts.
They have a high melting point.
They have a high density.
What is magnalium an alloy of?
Magnesium and manganese.
Magnesium and aluminium.
Magnesium and silver.
Magnesium and gold.
Aluminium is often used for plane body parts as it is:
Malleable
Low density
Has a high melting point
Is brittle
An alloy tends to be harder than a pure metal as:
Particles are different sizes.
Carbon gives this property.
Layers are disrupted.
Layers of particles cannot slide over one another.
Which pair of values is most likely to be the melting point and the boiling point of sodium? Use the table below to help you.
59 and 910
113 and 735
98 and 890
134 and 1498
