Atoms and Elements 01

This KS3 Science quiz asks questions about atoms and elements. Atoms are part of elements and elements are listed in the periodic table. Did you know that atoms are so small, one million atoms in a row is roughly equal to the thickness of a piece of paper? Imagine that!

There were two accepted systems of numbering the periodic table, one of which called the noble gases group VIIIA, often changed informally to group 8 (most commonly used in the USA) and the other that called it group 0 (most commonly used in Europe). The naming of anything in chemistry now is governed by a single organisation IUPAC (International Union of Pure and Applied Chemistry) and they have simplified the group numbering, the noble gases have now become group 18. Groups are also often referred to by the name of the first element in the group - the noble gases could also be called the helium group.

Other than groups 1 and 2, all of the other group numbers have changed. For example the halogens are no longer officially group 7, they are group 17. At the moment, many school text books still refer to the groups by their old numbers and names though some schools (maybe even yours) may already have changed. For the time being, in these quizzes, we use the numbers used by science teachers in most schools and exams.

1.
What is listed in the Periodic Table?
Only compounds
Only elements
Only gases
Only metals
An element was defined by the famous scientist Robert Boyle in 1661. The ancient Greeks thought there were four elements - fire, earth, air and water. Nowadays, we know that not a single one of those is actually an element. Fire is something burning, earth and air are mixtures and water is a compound. Believe it or not, there are still some people who believe in the ancient Greek ideas of the elements!
2.
In the periodic table, what is a period?
A horizontal row
A vertical line
The left hand side
The middle block
A group is a vertical column of elements
3.
Which of the following elements is the odd one out and why?
Helium because it is a very light element.
Hydrogen because it is not a noble gas.
Krypton because it is used to kill superheroes.
Neon because it is the only element that flashes on and off.
The other three are all noble gases, hydrogen is a very odd element that doesn't really fit properly into any group of the periodic table
4.
Which of the following is a name for group 7 in the periodic table?
Alkali metals
Alkaline earth metals
Halogens
Noble gases
They are poisonous, coloured elements
5.
Which of the following is a name for group 2 in the periodic table?
Alkali metals
Alkaline earth metals
Halogens
Noble gases
These are harder than the Group 1 metals next to them
6.
Which of the following is a name for group 8 in the periodic table?
Alkali metals
Alkaline earth metals
Halogens
Noble gases
About the only thing that they will react with is the element fluorine
7.
Which of the following is a name for group 1 in the periodic table?
Alkali metals
Alkaline earth metals
Halogens
Noble gases
They are soft metals that react rapidly with water
8.
Which of the following is the symbol for sodium?
Na
S
Sd
So
The latin name for sodium is natrium
9.
Which of the following elements is a metal?
Magnesium
Nitrogen
Helium
Phosphorus
The others are non metals
10.
