- Periodic Table
- Symbols
- Every element in the Periodic
Table has a symbol.
- There are periods and
rows, to organise it.
- Combining Elements
- Reactions Between...
- Hydrogen and Oxygen
- Squeaky pop and some condensation.
- Hydrogen + Oxygen -----> Water
- Magnesium and Oxygen
- Very bright white flame and there
was a white solid left over.
- Magnesium + Oxygen -----> Magnesium Oxide
- Sodium and Chlorine
- White solid,smoke and an
orange-yellow flame.
- Sodium + Chlorine -----> Sodium Chloride
- Aluminium and Iodine
- Purple smoke, orange-white spark
and there was a white solid left over.
- Aluminium + Iodine -----> Aluminium Iodine
- Atoms,Elements and Compounds
- Deciphering the Names of Compounds
- Compounds of two elements have an -ide ending.
- Magnesium and Oxygen makes Magnesium Oxide
- Compounds made up of two elements plus
oxygen usually end in -ate.
- Copper, Sulphur and Oxygen makes Copper Sulphate
- Some compounds have common names
as well as chemical names.
- Water, Salt and Chalk
- Atoms Combining
- Atoms of one type combine to form molecules of an element.
- Atoms of two or more types combine to form molecules of a compound.
- Elements and Atoms
- A substance can not be an element and a compound at
the same time because an element has not only got one
type of atom but a compound has two types or more.
- A substance can not be an atom and a compound at the same time
because a single atom has only one type of atom but a compound
has two or more types of different atoms.
