Which of below correctly describes how the early Periodic table was used to classify the known elements and was used to predict the properties of the elements that had not yet been discovered?
Elements in the same Period displayed similar properties.
The arrangement of the known elements provided trends in behaviour which was used to make predictions about the unknown elements.
Elements in different Groups displayed similar properties.
There is no rules detected.
Potassium and krypton are elements in Period 4. Potassium is at the beginning of the period and is more metallic than krypton which is at the end of the period. What makes potassium more metallic than krypton?
It has less electrons than krypton.
It has less protons than krypton.
It has less electron shells.
It has less outer shell electrons.
The elements of the Periodic table can be broadly classified into two main characters which are metals and nonmetals. Which statements are correct?
Magnesium is less metallic than silicon.
Boron is more metallic than lithium.
Carbon is less metallic than beryllium.
Sodium is less metallic than aluminium.
The metallic character of the elements changes as you move across a period.
Which statement explains this trend?
The mass number increases as you move across.
The physical properties change as you move across.
The tendency to lose or gain electrons changes moving across.
The atomic number changes as you move across.

Which of the following statements are correct about elements W, X, Y and Z?
Z is found in nature in the elemental state
W is less metallic than X
Z have more electron shells than Y
Y forms a covalent compound with X
Which statement explains the observation that as you move down a group on the Periodic table the metal elements become more metallic in character?
Electrons are more easily gained due to increasing atomic radius.
Electrons are more easily lost due to increasing atomic radius.
The elements are heavier due to the atomic number increasing as you move down a group.
The elements are heavier due to the mass number increasing as you move down a group.

The reactivity of the halogens decreases moving down the group.
Which statement explains this observation?
Decreasing distance between the nucleus and outer shell makes it easier for the atom to attract electrons.
Increasing distance between the nucleus and outer shell makes it easier for the atom to attract electrons.
Decreasing distance between the nucleus and outer shell makes it harder for the atom to attract electrons.
