Worksheet Overview

QUESTION 1 of 10

Group One elements in the Periodic Table are called the alkali metals. They are lithium, sodium, potassium, caesium and rubidium. They all react vigorously with air and water, so they have to be stored in oil.


Sodium is more reactive than lithium and potassium is more reactive than sodium. You can tell, because potassium reacts extremely vigorously and quickly with water, whereas lithium less quickly and vigorously, with sodium somewhere in the middle of the reactivity series. As for caesium and rubidium - their reaction is.... explosive!


Alkali metals have a lower density than water, so they float when they react with it. The products of this reaction are the metal hydroxide (for example, sodium hydroxide when sodium reacts) and hydrogen.


Here is the general chemical equation. All you would have to do is substitute the word 'metal'; with the name of the metal you are writing the reaction about:


metal + water  metal hydroxide + hydrogen

 


Group One metals also react with Group Seven non-metals (for example: chlorine, bromine, iodine) and they make a compound which combines both of them. An example is:


potassium + iodine potassium iodide


Note how the endings change: -ine becomes -ide.


Group Seven elements are called halogens and the compounds they make with Group One elements are called metal halides.


Metals form compounds with the carbonate group (-CO3), the metal carbonates. Metal carbonates decompose (break down) with heat and form a metal oxide and carbon dioxide:

 


Rusting is a form of chemical reaction of metals with oxygen and water. The chemical equation for rusting of iron is:


iron + oxygen + water hydrated iron(III) oxide


Iron(III) is one of the two types of iron; the other one is Iron(II). Rusting is an example of oxidation. The name comes from the reaction with oxygen to form an oxide.


Metal compounds react with acids. Specifically:


 metal oxide + acid salt + water


Example: copper oxide + hydrochloric acid copper chloride + water

 

metal hydroxide + acid salt + water


Example: sodium hydroxide + nitric acid sodium nitrate + water

 


metal carbonate + acid salt + water + carbon dioxide


Example: calcium carbonate + sulfuric acid calcium sulfate + water + carbon dioxide

 

A metal oxide is a compound of a metal with oxygen. A metal hydroxide is a compound of a metal with the hydroxide group (-OH). A salt is a compound made of a metal and a non-metal. Hydrochloric acid gives chlorides, nitric acid gives nitrates and sulfuric acid gives sulfates.

  • Question 1
What is the other name for Group One elements?
CORRECT ANSWER
alkali metals
EDDIE SAYS
Group 1 elements are called Alkali Metals.
  • Question 2
Which is the least reactive alkali metal?
CORRECT ANSWER
lithium
EDDIE SAYS
Lithium is the least reactive alkali metal. Caesium is the most reactive metal.
  • Question 3

Tick two products of the reaction of lithium with water.

CORRECT ANSWER
hydrogen
lithium hydroxide
EDDIE SAYS
Two products of the reaction of lithium with water are hydrogen and lithium hydroxide.
  • Question 4

Select the two halogens.

CORRECT ANSWER
bromine
chlorine
EDDIE SAYS
Bromine and chlorine are halogens (Group seven elements).
Potassium is an alkali metal (Group one).
  • Question 5

Select the two reactants of the reaction that produces lithium chloride.

CORRECT ANSWER
lithium
chlorine
EDDIE SAYS
In order to get lithium chloride, one must react lithium and chlorine. You can tell by the name of the product, which is a combination of lithium and chlorine.
  • Question 6

What would be the oxide forming from the thermal decomposition of copper carbonate?

CORRECT ANSWER
copper oxide
EDDIE SAYS
The oxide forming from the thermal decomposition of copper carbonate is copper oxide.
  • Question 7

How does the hydrated Iron(III) form?

CORRECT ANSWER
rusting
EDDIE SAYS
Hydrated iron(III) oxide forms through rusting.
  • Question 8

What salt would be produced if copper oxide reacts with nitric acid?

CORRECT ANSWER
copper nitrate
EDDIE SAYS
Copper nitrate is produced when copper oxide reacts with nitric acid. The name is a combination of copper and nitric acid.
  • Question 9
What metal hydroxide needs to react with sulfuric acid to give iron sulfate?
CORRECT ANSWER
iron hydroxide
EDDIE SAYS
Iron hydroxide needs to react with sulfuric acid to give iron sulfate.
  • Question 10

What acid reacts with potassium carbonate to give potassium chloride?

CORRECT ANSWER
hydrochloric acid
EDDIE SAYS
Hydrochloric acid reacts with potassium carbonate to give potassium chloride.
