Metals can be beaten into thin sheets. This property is called malleability.
The ability of metals to be drawn into thin wires is called ductility.
Gold is the most ductile metal.
The best conductors of heat are silver and copper.
The metals that produce a sound on striking a hard surface are said to be sonorous.
All metals except mercury exist as solids at room temperature.
Almost all metals combine with oxygen to form metal oxides.
Metals such as potassium and sodium react so vigorously that they catch fire if kept in the open.
Metals react with water and produce a metal oxide and hydrogen gas.
Metals react with acids to give a salt and hydrogen gas.
Sodium and chloride ions, being oppositely charged, attract each other and are held by strong electrostatic forces of attraction to exist as sodium chloride (NaCl).
Ores mined from the earth are usually contaminated with large amounts of impurities such as soil, sand, etc., called gangue.
Metals low in the activity series are very unreactive.
The metals in the middle of the activity series such as iron, zinc, lead, copper, etc., are moderately reactive.
The sulphide ores are converted into oxides by heating strongly in the presence of excess air. This process is known as roasting.
The carbonate ores are changed into oxides by heating strongly in limited air. This process is known as calcination.
