4.
In the diagram, two parts of the Periodic Table are shaded, X and Y. The elements in which shaded part would you expect to react in similar ways, and why?
Dr Dabour Hub Academy - figure 2
Y, because it is a group
X, because it is a group
X, because it is a period
Y, because it is a period
5.

11.
Ella claims: "All non-metals are gases." Which element in the table is the best evidence that she is wrong?
Oxygen, a gaseous non-metal
Sodium, a solid metal
Carbon, a solid non-metal
Hydrogen, a gaseous non-metal
12.
A party shop needs a gas to fill balloons that float. Using the table, which gas is the best choice and why?
Hydrogen, because it is the lightest and burns well
Oxygen, because it is needed for burning
Chlorine, because it kills bacteria
Helium, because it floats and is unreactive
13.
The table lists the types of atom found in four substances. Which two substances are elements?
Diamond and oxygen gas
Water and sea water
Diamond and water
Oxygen gas and sea water
14.
Aaron is labelling element samples with their symbols. Which pairing is correct?
Chlorine – C
Helium – H
Iron – Ir
Magnesium – Mg
15.
Consider how each element is used or behaves. Which pairing is correct?
Oxygen – kills bacteria in water
Helium – unreactive, used in balloons
Magnesium – magnetic, used to make steel
Chlorine – lightest element, used as a fuel
16.
Think about where each element sits in the Periodic Table. Which pairing is correct?
Sodium – group 1, a metal on the left
Carbon – group 7, a metal on the left
Iron – group 8/0, a noble gas
Oxygen – group 1, a soft metal
17.
Each pairing gives an element and its state at room temperature. Which pairing is correct?
Magnesium – a liquid at room temperature
Helium – a solid at room temperature
Chlorine – a gas at room temperature
Carbon – a gas at room temperature
18.
Kim wanted to write the symbol for cobalt, Co, but wrote CO instead. Why is CO wrong?
Symbols must always be written in small letters only
A capital O starts a new symbol, so CO means carbon and oxygen
CO is correct because capital letters are always allowed
Cobalt has no symbol because it is not in the Periodic Table
19.
Element Z is in group 1, the same group as sodium. Which description of Z is most likely?
A soft metal that reacts very readily
An unreactive gas used in balloons
A non-metal that is needed for burning
A hard, magnetic metal used to make steel
20.
Arjun is told that an element is in group 7, period 3. How should he find it in the Periodic Table?
Look along row 7 until he reaches the third column
Count 73 elements from the start of the table
Look down column 7 until he reaches the third row
Look in the third column of the transition metals
21.
Why was argon placed in the same group as helium when it was discovered?
Its symbol also starts with a capital letter
Like helium, it is an unreactive gas
It was discovered in the same year as helium
Both elements are shiny metals
22.
Students tested five metal samples – iron, magnesium, sodium (by the teacher), copper and aluminium – with a magnet. Only iron was attracted. What is the best conclusion?
All metals are magnetic, so the magnet must be faulty
Only iron is a metal; the other four are non-metals
Magnetic elements are always found in group 1
Being magnetic is a property of iron, not of all metals
