What type of elements are found on the left-hand side of the periodic table?
Metals
What type of elements are found on the right-hand side of the periodic table?
Non-metals
What kind of compound is formed when a metal reacts with a non-metal?
An ionic compound
When naming compounds made from a metal and a non-metal, which element is named first?
The metal
What usually happens to the ending of the non-metal's name when it forms a compound?
It changes to -ide
Why does sodium chloride end in '-ide'?
Because chlorine is a non-metal and non-metals change their ending to -ide in compounds.
Which part of the compound name tells you it contains a metal?
The first word / the metal name
What is the name of the compound NaCl?
Sodium chloride
What is the name of the compound MgO?
Magnesium oxide

Magnesium nitride
What is the name of the compound formed from aluminium and sulfur?
Aluminium sulfide
Is the naming of NaCl as sodium chlorine correct or incorrect?
Incorrect; it should be sodium chloride.
Is the naming of MgO as magnesium oxide correct or incorrect?
Correct.
How can you tell from the name potassium iodide that this compound contains a metal and a non-metal?
The name contains potassium (a metal) and iodide (a non-metal ending in -ide).
Why is the compound made from calcium and oxygen called calcium oxide and not oxide calcium?
The metal is named first, followed by the non-metal with '-ide'.
What is the name of the compound with the formula AlN?
Aluminium nitride.
Is iron a metal or a non-metal?
