Metals and non-metals have different properties and different reactions. These differences in reactivity depend on where an element is placed in the periodic table.
Where do non-metals appear in the periodic table?
On the left
In the middle
On the right
Which of these are typical properties of metals?
High melting point and brittle
High density and ductile
Poor conductor of electricity and shiny
Metals are malleable. What does malleable mean?
A metal can be hammered flat
A metal can conduct electricity
A metal can be drawn into wires
A metal is burned in oxygen to form an oxide. The oxide dissolves in water and a few drops of universal indicator are added. What colour does the indicator turn?
An element has three electrons in its outer electron shell. What type of element is it?
What happens to the outer shell of a non-metal when it reacts?
It loses electrons
It gains electrons
It keeps the same number of electrons
Group 2 is a group of metals. What is the trend in reactivity on going down group 2?
The elements become more reactive
The elements become less reactive
The elements do not change in reactivity
What is used in the test for hydrogen?
A glowing splint
A lighted splint
What is the result of the test for oxygen?
Relighting of a glowing splint
A squeaky pop
Litmus paper turns red
Chlorine gas turns damp litmus paper white. What does this show?
