Q

Contracts

A

Shorten or become smaller in size

17
Q

Alchemists

A

Olden-day ‘chemist’ who mixed chemicals and tried to change ordinary metals into gold. Alchemists also tried to tell the future.

18
Q

Investigations

A

Activity aimed at finding information

19
Q

Observations

A

Information obtained by the use of our senses or measuring instruments

20
Q

Scientists

A

People skilled in or working in the fields of science; scientists use experiments to find out about the material world around them

21
Q

Elements

A

Pure substance made up of only one type of atom

22
Q

Atoms

A

A very small particle that makes up all things. Atoms have the same properties as the objects they make up.

23
Q

Atomic Number

A

Number of protons in the nucleus of an atom. The atomic number determines which element an atom is.

24
Q

Chemical Symbol

A

The standard way that scientists write the names of the elements, using either a capital letter or a capital followed by a lowercase letter. For example, carbon is C and copper is Cu.

25
Q

Compounds

A

Substance made up of two or more different types of atoms that have been joined (bonded) together

26
Q

Bonded

A

Force that holds particles of matter, such as atoms, together

27
Q

Mixtures

A

A combination of substances in which each keeps its own properties

28
Q

Hydrogen

A

The element with the smallest atom. By itself, it is a colourless gas and combines with other elements to form a large number of substances, including water. It is the most common element in living things.

29
Q

Oxygen

A

A gas in the air (and water) that animals need to breathe in; made up of particles with two oxygen atoms. Plants produce oxygen as part of photosynthesis.

30
Q

Metals

A

Elements that conduct heat and electricity; shiny solids that can be made into thin wires and sheets that bend easily. Mercury is the only liquid metal.

31
Q

Non-Metals

A

Elements that do not conduct electricity or heat. They melt and turn into gases easily and are brittle and often coloured.

32
Q

Metalloids

A

Elements that have the appearance of metals but not all the other properties of metals

33
Q

Periodic Table

A

A table listing all known elements. The elements are grouped according to their properties and in order of the number of protons in their nucleus.

34
Q

Group

A

In the periodic table of elements, a single vertical column of elements whith a similar nature

35
Q

Inert

A

Not reactive

36
Q

Noble Gas

A

Elements in the last column of the periodic table. They are extremely inert gases.

37
Q

Molecules

A

Two or more atoms joined (bonded) together, forming a small particle
