Total questions: 16
Worksheet time: 45mins
Which of the following statements is true about the Periodic Table of Elements?
There are 18 Groups and 8 Periods in the Periodic Table of Elements
Groups are the horizontal rows of elements
Periods are the vertical columns of elements
Elements that have the same number of valence electrons are arranged in the same group
The following statements refer to the contributions of a scientist in the development of the Periodic Table. Plotted the graph of the atomic volume against the atomic mass the elements. Successful in showing the properties of the elements formed a periodic pattern with their atomic masses.
Who was the scientist?
Lothar Meyer
Henry Moseley
John Newlands
Dmitri Mendelev
The size of atoms in Group 18 get larger down the group. This is caused by
the increase in the number of electrons
the decrease in melting point and boiling point of the elements
the increase in solubility rate in water
the increase in the number of shells filled with electrons
During a chemical reaction, every alkali atom in Group 1
releases one valence electron to achieve duplet or octet electron arrangement
releases two valence electrons to achieve duplet or octet electron arrangement
releases three valence electrons to achieve duplet or octet electron arrangement
releases four valence electrons to achieve duplet or octet electron arrangement
The reactivity of Group 17 elements decrease down the group. This is caused by
the decrease in atomic size down the group
the decrease in boiling point and melting point
the colour of element getting darker down the group
the attractive force of the nucleus on the electron getting weaker
The change in physical properties of the elements across Period 3 from left to right in the Periodic Table of Elements is due to
the increase in proton number
the increase in the radius of atoms
the decrease in electronegativity
the change in physical state from gas to liquid and finally to solid
This element has two or more oxidation numbers and forms compounds that have different colour. This element is
metalloid element
amphoteric element
transition element
alkaline earth metal element

Nickel
Platinum
Metal
Vanadium(V) oxide

Which of the following is a monoatomic gas?
Oxygen
Fluorine

Nitrogen
Helium gas is used to fill weather balloons because of its inert property. Which of the following is the
best explanation of the property?
Has low density
Exists as monoatomic gas

Placed in Group 18 in the Periodic Table
Which statement explains why the reactivity of Group 1 elements increases when going down the group?
The physical state of the elements changes from gas to liquid then to solid at room temperature
The attractive force between valence electron and the nucleus becomes stronger
The valence electron gets further away from the nucleus
The melting points of the elements decrease
Diagram above shows the method used to store an element. Which of the following explains why the method is used?
To avoid from reaction with sunlight
The element is toxic and dangerous
The element is reactive and volatile
To avoid from reaction with oxygen in the air
