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
